An old friend of mine, a seemingly smart guy, came to visit me and somehow casually mentioned that he had bought a cool voltage stabilizer for his TV. In response to my reasonable question - why did he do this, he was surprised and immediately began to list the “indisputable” advantages of this acquisition. However, after just 15 minutes of argument, his confidence faded somewhat.
In general, it is surprising how much we are influenced by marketing ploys. Even seemingly intelligent people with developed critical thinking are easily fooled by various advertising tricks and sweet assurances from salespeople. In the case of stabilizers, I think memories from the distant past came into play - from the good old Soviet Union.

Power surges are a nuisance familiar to residents of large cities and small towns. They occur due to accidents on the line during periods of bad weather with heavy rain, thunderstorms and wind. And most importantly, such a nuisance is always unexpected, so there is no way to turn off all household appliances in a timely manner. Moreover, each such leap brings closer the “death” of the TV, computer, washing machine. Therefore, it is important to select and install a voltage stabilizer for your TV in advance. Especially if you don’t plan to update the equipment in your home in the next couple of years.

What are stabilizers and are they needed?
Uninterruptible power supply systems are devices for maintaining stable voltage in conditions of voltage fluctuations. The task is to increase or decrease the intensity of the current supply within the optimal limits of 220 V. And turn off the supply when the intensity level reaches 160 V or less or 255 V or more.
They are included in the basic configuration of any laptop. A stabilizer for the TV has to be purchased separately.
According to the connection method, stabilizers are networked, where the connection is provided for each individual device. Or main ones - connected to all electrical networks leading to the house or entrance.
Advice. If you have a large amount of expensive equipment in your home, you should think in advance about a separate main uninterruptible power supply. It is installed on the cable entering the home. And so it protects all equipment, not just TV.
Which brand of voltage stabilizers is best to choose for your home?
This TOP describes the advantages and disadvantages of products from 5 competing companies. There are companies here that offer low-cost, premium, and mid-priced options, depending on their characteristics. Despite the gap in cost, each of the brands presented in the rating has earned a great name for itself in Russia and is among the leaders according to customer reviews. Here are the brands we will talk about:
- Resanta - the brand offers devices with a good combination of price and quality. They support the operation of both small and more powerful electrical appliances, preventing them from breaking down during current surges in the network. In most cases, single-phase units are offered here. The brand has both relay models and options with double energy conversion.
- Energy - the history of this company began in 2000, at that time it supplied equipment to the market from other companies, but over time it retrained as a manufacturer of electrical devices. At the moment, it has its own design department and factories located in Russia and China. When creating products, it is guided by the principle of reasonable prices, safe use of goods and their high quality.
- Rucelf is almost the main competitor of Resanta, offering the best voltage stabilizers in terms of price and quality ratio, which is optimal here. That is why his products are in high demand on the market. They are safe and easy to use, easy to install and have a decent design. They are used both regularly and periodically. The brand takes care to protect its devices from overheating, overloads and extraneous noise, so the service life of the products exceeds 10 years.
- Calm - this brand produces both budget options and mid-range, as well as premium models. Among them, double conversion devices are especially popular, which are almost as good as uninterruptible power supplies. There are two groups available here: “InStab” and “InStab+”, developed using inverter technology. With their help, the adjustment process occurs in several stages, and in the reviews there are no complaints about the response time; here it is minimal.
- Sven - the company's products can be used both in apartments and in houses or offices. It has affordable prices and at the same time decent quality. This is indicated by the fast switching time between windings of a maximum of 10 ms, long cables on average 1.7 m, resistance to low temperatures down to -40 degrees and high levels of moisture - up to 80-90%. There are both wall-mounted and floor-mounted units, protected from impulse noise, overload, and overheating. Therefore, it is not at all strange that their service life is very long, on average 10 years.
The best electricity meters
Do all TVs need “stability”?
The question of purchasing a 220V voltage stabilizer for a TV has been around since the days of large tube models. With each current surge, the image on the display deteriorated, became distorted, and the color changed. Often after a thunderstorm it was necessary to repair or send the TV for repairs.
Modern technology based on matrices such as LED, LCD and plasma is equipped with a switching power supply. It supports current drops in a fairly wide range: from 170 to 250 V. As soon as the values go down or up, the TV automatically turns off. But, if for some reason this does not happen, there is a high probability of breakdown and subsequent repair of the TV.
Some manufacturers, for example, Samsung and LG, produce separate equipment for their TV models. This type of TV protection against power surges is reliable, but costs several times more than analogues from other companies.
It turns out that despite the built-in protection against current surges in TVs, they need a separate stabilizer, especially if the light bulbs in the house blink very often and the lights turn off.
When exactly do you need an uninterruptible power supply?
Despite the presence of a built-in stabilizer in LCD and LED TVs, there are situations when additional equipment is definitely required:
- Constant power surges in the house due to old wiring, frequent thunderstorms and winds.
- A private house where there are always problems with the intensity of the current supply.
- There are often renovation works or construction of new houses going on nearby - there is a high probability that cables will be damaged during construction.
Before purchasing a device, you can measure the total voltage in the network in the house for one or two days. To do this, you need to purchase or borrow a tester from someone. And check the indicators every 1-2 hours.
Such an analysis will help to understand whether a stationary or mainline device is needed. After all, it is better to protect once than to repair appliances in the house many times.
Important! The main uninterruptible power supply is mounted as close as possible to the switchboard. It is advisable to install it immediately after the meter.
Do not confuse pixel burnout on the matrix with the consequences of power surges. Pixels are control transistors. And they do not fail due to voltage. But a complete failure or disappearance of the picture as a whole is already a sign of voltage drops.
What characteristics should you look for when choosing a voltage stabilizer?
Type. Voltage stabilizers, depending on the basic principles of operation, can be divided into several types:
- relays are one of the most affordable devices on the market, which compensate for the low accuracy of the output voltage with high operating speed and a wide voltage range;
- electromechanical - more accurate, but not as fast and adaptive as relay analogues;
- hybrid (combined) - these voltage stabilizers combine the advantages of relay and electromechanical devices;
- electrodynamic - the next stage in the evolution of electromechanical stabilizers: accurate, reliable and expensive;
- electronic ones are also far from the cheapest, but definitely one of the most convenient, accurate and fast stabilizers;
- inverter stabilizers, which are considered the most modern and are distinguished by a wide range of operating voltages, small errors and very low delays in operation - at the expense, of course, of a high price.
Phasing . As a rule, single-phase electrical wiring is used in city apartments, but to power private homes and industrial equipment, three-phase wiring is often used, which allows the use of a voltage of 380 volts rather than 220. A stabilizer with the wrong phase simply will not work, so this point must be kept in mind when choosing.
Power . Perhaps the most important parameter when choosing a voltage stabilizer. If its power is not enough to serve all consumers, the stabilizer will fail. Accordingly, the power consumption must correspond to the capabilities of the device (plus it is advisable to add another 20-30% - just in case).
An important aspect: power can be not only active, but also reactive. High starting current, which characterizes devices with electric motors, such as vacuum cleaners and electric meat grinders, can damage the stabilizer. For such reactive consumers, it is worth taking into account not only the active power, measured in watts, but also the total power - in volt-amperes. To calculate the latter, it is necessary to divide the active power by a special coefficient specified in the device passport (for simplicity, it can be taken equal to 0.7 or 0.8).
Stabilization accuracy . High accuracy of stabilization means that the stabilizer will produce a voltage as close as possible to the reference 220 V. For devices of different types, the accuracy can range from 2-10%.
Stabilization speed. Typically it ranges from 5 to 20 ms, depending on the type and features of the specific device. Of course, the faster the stabilizer responds to voltage surges, the better.
Operating and maximum voltage range. The possibilities of stabilizers are not limitless: they can only normalize voltage at certain levels. Moreover, the devices can withstand extreme, peak values for only a short time, so you should pay attention specifically to the range of operating voltages, which will be easier for the stabilizer to cope with.
Indication . It is desirable that the stabilizer be equipped with an LCD display that will transmit voltmeter readings (if possible, not only at the output, but also at the input). However, in the simplest models, LED displays are used instead of screens. It's not as informative, but it's cheap and reliable.
Installation . Stabilizers can be placed on the floor, on the wall or installed in special racks.
Types of equipment and its features
All stabilizers for TV and other equipment are divided into the following subtypes:
- Step or relay options. Their operating principle is based on switching the windings of a working transformer. If the input voltage changes, the relay closes, which reduces the amount of sinusoidal voltage in the network. The setting in such models occurs abruptly and is accompanied by a specific sound that appears when the relay contacts close. Such options are perfect for networks where surges occur very frequently and over a wide range of volts. In terms of cost, the equipment is the cheapest.
- Electronic uninterruptible power supplies equalize the voltage using triac or thyristor switches. The equipment is quite expensive. But it works silently and with instant adjustment of input parameters.
- Electromechanical devices or servomotor, servo-drive options. They are adjusted using the movement of carbon contacts along the winding due to the operation of the electric drive. Stabilizers of this class have an average price. Adjustment of indicators is smooth. The design has small dimensions. The disadvantages include: it is quite noisy and has a low reaction speed.
- Ferroresonance options have a long service life and low price. They precisely regulate the input parameters. But they have an impressive size, weight and loud noise during operation.
- Inverter stabilizers convert voltage using two methods. At the input it changes to a constant, at the output it changes to a variable. The devices operate absolutely silently. And they are reliably protected from any external interference and power surges. But at the same time, their cost is the highest of all options.
All of these stabilizers are suitable for installation before a TV or other equipment. With optimal technical parameters, they can be installed as main lines and protect the entire line. Moreover, the cost of the latter is much higher than a simple TV stabilizer.
The best electronic voltage stabilizers - ultra-precise devices
A little higher we looked at the rating of popular relay-type stabilizers. Electronic stabilizers with step regulation are considered more modern and expensive. The switching of turns in such devices is controlled electronically by thyristors and triacs. Thanks to this, the speed of processing disturbances increases, the stabilization error decreases, and the noise of the device decreases. Electronic stabilizers are perfect for use at home and in the office.
5 Energotech NORMA 9000
The Energotech NORMA 9000 electronic stabilizer is disconnected from the network when the voltage drops to a critical level of 60V. Up to this limit, its transformer is capable of ensuring the operation of the device and generating an output voltage of 220V. In this case, the error does not exceed 7%. This performance was achieved through 9 stages of stabilization. The equipment will provide electricity to almost all home appliances - 9 kW of power is enough for a washing machine and an oven, not to mention a refrigerator, TV or gas boiler. Installation in a country house will deprive the owner of many problems, especially if the electrical network to which the house is connected is in a worn-out condition.
The manufacturer, confident in the high quality of components and assembly, provides a warranty for a fairly decent period - 5 years. Thyristors operate almost silently, and, judging by the reviews of the owners, in full accordance with the declared parameters. Energotech NORMA 9000 also provides protection against short circuits and overheating of the transformer winding, removes interference and stabilizes the output signal shape (sinusoidal current), which has a positive effect on the service life of household appliances and electronics. Many also note the versatility of the ergonomic case, which can be wall-mounted.
4 Systems Ultra-M 9000
The single-phase electronic thyristor-type stabilizer Systems Ultra-M 9000 is capable of equalizing the incoming voltage within the range of 110-290V with an accuracy of 5%, thanks to a 16-step stabilization system. Despite the minimal energy consumption, this device is equipped with a unique transformer that has a triple power reserve. With possible input voltage limits from 60 to 300V, the stabilizer guarantees an output of 209-230V, which provides reliable protection for all electrical appliances operating at home. At the same time, thanks to the presence of microprocessor control and thyristor switches, this device produces a minimum of noise.
The Systems Ultra-M 9000 voltage stabilizer has the longest service life, designed for a minimum of 10 years of continuous operation under maximum load conditions. This is facilitated by a durable metal case and multi-level protection against short circuits, pulse currents and overloads. This stabilizer will be the best solution to problems that may arise due to inconsistent voltage levels at the dacha or in a country house. With it you don’t have to worry about the uninterrupted operation of the refrigerator and gas boiler during the owner’s absence.
3 Energy Classic 7500
Energy Classic 7500 is an electronic stabilizer with a total power of 7500 VA. Third place in our ranking. Has the lowest shutdown threshold in the rating. This stabilizer is best suited for a house or apartment where there is often low voltage in the network. “Energy” is turned off when the voltage drops to 60 V. In the TOP-3, this stabilizer has the best response time, that is, the device begins to compensate for the voltage difference the fastest. The delay between a change in input voltage and the start of its correction is only 20 ms. The efficiency of the device is 98%, which is again the best indicator in the trio under consideration.
Energy Classic 7500 is a very light stabilizer for its power. Weight is only 20 kg. Thus, it can be mounted on the wall, saving space in the room. According to the manufacturer, the Classic 7500 has a resource of 60,000 hours or about 20 years of operation. From user reviews, it is worth noting such advantages of the stabilizer as excellent design and silent operation.
2 Lider PS10000W-50
Lider PS10000W-50 is the most expensive device in our rating. The uniqueness of this stabilizer is that it can operate over a very wide input voltage range. Due to the boost transformer, the device can operate without loss of power with a minimum voltage of 128 V and a maximum voltage of 320 V. “Leader PS10000W-50” is a completely autonomous electronic device, with a low noise level and does not require maintenance. It does not have a relay and a servo drive, something that most often wears out in single-phase stabilizers.
In the reviews of owners who chose this voltage normalizer to protect the electrical network of their home, there are practically no complaints or complaints. Most often, many users indicate that after installing the stabilizer they completely forgot about its existence and any anomalies - stable 220V reliably protects the refrigerator, gas boiler, TV and other equipment.
1 PROGRESS 8000TR
PROGRESS 8000TR is a modern, high-quality device from a Russian manufacturer. Number one in the ranking of the best electronic stabilizers. This is a very productive device with a total power of 8000 VA. Excellent for apartments and houses, where there is often an overvoltage of up to 305 V. In our rating, this stabilizer has the best stabilization speed, equal to 500 V/s. It is known that the higher this indicator, the faster the device responds to voltage changes.
It is impossible not to mention the best indicator for stabilization accuracy. The error of PROGRESS 8000TR is only 3%. Among the shortcomings, according to user reviews, we note the excessive noise of the PROGRESS 8000TR stabilizer. Installation in a separate, non-residential premises is recommended.
The best electromechanical voltage stabilizers with power up to 10 kW
Electromechanical stabilizers are essentially step-up transformers, with advantages and disadvantages arising from their design. Despite the obsolete design and the arrival of more developed types on the market, they are still very popular and compete with popular electronic and relay models. The key feature of electromechanical stabilizers is that they independently regulate the voltage in the network, unlike the same relay competitors.
5 CALIBER ASN-10000/1
One of the budget electromechanical stabilizers is presented in the form of a floor-mounted structure. It has all the necessary degrees of network protection from critical loads; this device is capable of maintaining an output of 220V with an input voltage of only 140V. The front panel contains a digital display of operating parameters and toggle switches for controlling the bypass and connection to the general network, as well as the package fuse.
Despite the parameters that are quite decent for an electromechanical stabilizer, there is one value, the size of which largely determines such an affordable cost of protective equipment - this is the response time. In CALIBR ASN-10000/1 it is as much as 500 ms, which is simply a huge indicator in comparison with its closest competitors. However, it is perfect for a summer house or country house - this stabilizer can protect a TV, refrigerator and even a gas boiler.
4 Sturm! PS9315
The most optimal performance indicators are made by Sturm! PS9315 is a fairly popular stabilizer for installation in a country house or in a private house. Its advantage in the form of affordable cost is almost undeniable. However, floor placement and the heaviest weight (57 kg) in the category deprive the owner of the opportunity to compactly install the device in the hallway by hanging it on the wall. This stabilizer requires a separate place, and simply placing it in a corner will not work - the side walls have perforations for air access, and should not be limited in any way.
In terms of performance, for its price the Sturm! PS9315 is quite good. It maintains stable 220V (+-3%), even when the voltage at the entrance to the house drops to 140 V. This, of course, extends the life of the refrigerator, gas boiler and any other expensive equipment. Owners in their reviews indicate fairly serious protection from external factors. Thus, the stabilizer can operate in rooms with humidity up to 95% and air temperature of at least -5 °C, which allows you to install the device in an unheated dressing room at home (of course, not in the northern regions of the country).
3 IEK Shift 10 kVA
A single-phase electromechanical stabilizer will completely protect all equipment in a private building or apartment. The possibility of wall placement and dimensions that are quite compact for such power allow you to install the IEK Shift 10 kVA without any problems, even in a small hallway. Modern appearance, low noise level and high performance are considered the strengths of this model.
Maintaining an output voltage of 220V (the maximum possible deviation does not exceed 3%), the stabilizer will operate at 120V in the general network, which will save the owner from problems such as a burnt-out refrigerator or gas boiler. Particularly relevant is the installation of the device in a country house, where the electrical network quite often operates with abnormal fluctuations. Owners who have chosen this device indicate in their reviews that the stated characteristics fully correspond to the real state of affairs. The stabilizer reliably protects equipment from voltage surges and short circuits. During peak surges that it cannot cope with (more than 250V), the device simply turns off the power supply until the network parameters are normalized.
2 RESANTA ACH-8000/1-EM
An interesting model of the voltage stabilizer ACH-8000/1-EM from Latvian has stopped one step away from the leading position. The active power of this device is 8 kW, and the operating voltage range of the network varies from 140 to 260 V - optimal indicators for connecting a large number of small household electronics or high-power equipment within country houses (or medium-sized offices). The main advantage of this device is the stabilization error of 2% - relative to the leader in the rating, the gain is small (only 1.5%), but for powering sensitive (delicate) equipment such a spread can be very significant.
The stabilizer also has a Bypass mode, when turned on, it turns into a kind of passive element through which electricity is transited with the network voltage indicator. RESANT ACH-8000/1-EM has no obvious weaknesses - the stabilization device has three-level protection, a high efficiency rate (97%), low cost and prevalence in the domestic market... the only thing missing is popularity among users.
1 RUCELF SDWII-12000-L
RUCELF SDWII-12000-L is one of the best stabilizers in its class, which is naturally confirmed by its leading position in our rating. According to users, the limit of applicability of this device is country or country houses, where the voltage is often subject to significant changes. The stabilizer has excellent performance characteristics: an active power of 10 kW and a small stabilization error (only 3.5%) allow you to connect a significant amount of electronics to the device without fear for its safety. It is also important that the efficiency of the model is a brilliant 98% - in other words, the device operates with virtually no power losses.
RUCELF SDWII-12000-L has four levels of active protection: against short circuit, against overheating, against overvoltage and against interference. If any malfunction is detected, the stabilizer can be switched to Bypass mode, which is essentially a transit mode, in which the device will turn into a passive element of the network. Fortunately, such situations happen extremely rarely.
What are network filters
Modern TV models are equipped with a surge protector - internal protection against power surges. But over time it breaks down and requires replacement. Therefore, it is recommended to take expensive TVs for diagnostics at least once a year to avoid problems with network surges.
Such network voltage stabilizers for LCD and LED TVs include:
- Varistors - they provide resistance at very high pressure, taking it upon themselves. In this case, they usually burn out. The result is reliable, but disposable protection.
- LC filters remove high frequency interference due to the presence of capacitor coils and inductance. These are reusable and fusible fuses. They have a small button on the body. When the voltage exceeds the norm, the button is pressed and opens the target. The device operates automatically. But to start the work, you need to return the button to its initial position.
- Gas dischargers. They are equipped with gas-discharge electrodes along with a varistor. They take on the voltage and quickly eliminate the potential difference.
Important! Absolutely all network filters are equipped with grounding. A good manufacturer will definitely indicate in the instructions which of the lines relates to varistor protection. If there is a varistor only between phase and ground, additional grounding will have to be done. But in the “phase-zero” option, nothing auxiliary is required.
The surge protector itself is a complex device that includes electronic components to suppress impulse noise. They prevent equipment from short-circuiting during voltage surges.
A TV stabilizer is a more complex device that protects against both low and high frequencies and impulse noise. And surge protectors only protect against high levels. Therefore, uninterruptible power supply systems work much better and longer.
Best Double Conversion Voltage Stabilizers
Such devices are widely known as inverters, which are effective, in particular, because they allow electricity to be stored for more stable operation of devices. Before adding a specific product to the rating, we studied 10 different products.
Calm IS1000
This is the best 220V voltage stabilizer for the home in terms of accuracy, which is 98%. Accordingly, the error in power supply normalization does not exceed 2%, which ensures reliable operation of electrical appliances even of high power. There is a transformer of a convenient shape, flat, which can be easily hung on the wall, however, it is white and gets dirty quickly. By the way, this is one of the few models in the rating that has forced cooling, which increases its service life.
The Stil IS1000 is also interesting because it can work with two sockets, and this makes it universal. But there are some restrictions on the operating temperature - the air should not be cooled below +5°C, otherwise it risks failure. Among other options in the TOP, it is distinguished by its wide range of input phase voltage, 90-310V, thanks to which it can be used in completely different networks.
Advantages
- The risk of short circuit is almost completely eliminated;
- Reliable overvoltage protection;
- There is no interference;
- Withstands overload for 5-10 seconds;
- Service life – up to 20 years;
- It hardly gets warm.
Flaws
- Weight 3 kg.
Equipment selection criteria
To understand which voltage stabilizer to choose for your TV, you need to know exactly the network parameters. Understand how strong and frequent changes are in the network. After all, all devices have different power, which must be combined with the parameters of the TV.
The main parameters that are taken into account when choosing a device include:
- TV power. It can be found out through the technical passport. And use it to select an uninterruptible power supply indicator.
- In rural areas, additional protection against short circuits is needed. There is a high risk of strong wind gusts and thunderstorms.
- Operation noise level. Important when installing in the house directly next to the TV. Loud noise can ruin your TV viewing experience.
- Network power level range. If the supply intensity in the region drops to 90V, then protection should be turned on against this indicator.
- The dimensions of the unit also matter. There is no point in buying a bulky device that will take up a lot of free space.
Important! When purchasing a stabilizer not only for a TV, but also for other household appliances, it is necessary to take into account the total power of all devices. And use it to select an uninterruptible power supply.
When all the parameters have been calculated, you can decide which manufacturer of stabilizer for your TV to choose. Domestic entrepreneurs offer high-quality devices at an affordable price. Chinese options are the cheapest, but not the most durable. European ones are the most expensive, but they also have high build quality and protection against network outages.
You can buy an uninterruptible power supply from the same company as the TV itself. But such models are usually much more expensive than their analogues. It is worth purchasing equipment in specialized stores. You need to order online carefully so as not to get a “pig in a poke.”
The best relay voltage stabilizers for 10 kW
A distinctive feature of these powerful stabilizers is their relatively affordable price and the ability to provide adequate protection of home electrical equipment from network overloads. The category presents the best models of this type.
5 Wester STW-10000 NP
The Wester STW-10000 NP stabilizer has the best response speed even to the most significant changes in the network. It is capable of equalizing the input voltage to the optimal value in less than 0.5 seconds, in the operating range from 140 to 260V. This device is permanently connected to the home network, since its parameters are quite sufficient to stabilize the voltage of the entire house, small office or cottage. Thanks to its high total power, Wester STW-10000 NP is able to protect any household and computer equipment from surges with a total consumption of 10 kW.
This relay stabilizer has a high degree of protection - if the input voltage exceeds the permissible limits, the device will completely turn off until the situation returns to normal. If the jumps turn out to be short-lived and insignificant, the stabilizer will continue to perform its task. This device also protects the home network from short circuits. The Wester STW-10000NP is controlled using toggle switches, and all the information necessary to monitor the situation is displayed on a digital display.
4 SUNTEK SNET-11000
This household network stabilizer is simply necessary in a country house or in a residential building. Several types of protection and voltage equalization to the norm of 220V will protect electronic devices and expensive household appliances, such as a refrigerator, washing machine or dishwasher, TV, air conditioner, etc. A special feature of this relay stabilizer can be considered the presence of a Bypass system, which allows you to separate a protected branch in your home network so that the power of the SUNTEK SNET-11000 is sufficient for expensive equipment.
In the reviews left, the owners positively evaluate the functionality of the device - it maintains the standard 220V (+-8%) in a secure network, while at the input to the device the drop can reach 120V. This is especially effective when a neighbor in the country uses a welding transformer. Overvoltage above 285V leads to protection activation and disconnection from the network, since the relay mechanism can miss such surges. At the same time, there is a fairly high noise level of its operation. However, this factor does not have a serious influence on the choice of the future owner, since the affordable cost fully compensates for it.
3 RUCELF SRWII-12000-L
The third place in the ranking of the best 10 kW stabilizers is occupied by the RUCELF SRWII-12000-L device. The model has slightly higher total power than its opponents - 12,000 VA. This will allow you to operate the device in networks with a slightly higher load (large household appliances, powerful electric motors). Its active power is standard for the top three - 10,000 W.
The device also has the best efficiency among competitors - 98%. We also note the presence of a startup delay, protection against short circuits, overheating and overvoltage. The only downside is the slightly inflated price. RUCELF SRWII-12000-L costs approximately 25–40% more than stabilizers from the Resanta and Era brands. The development of RUCELF stabilizers belongs to Russian engineers, but assembly is carried out in China.
2 Daewoo Power Products DW-TM12kVA
The Daewoo Power Products DW-TM12kVA relay stabilizer protects household equipment from overvoltage, overheating, network interference and short circuits. The response time to deviations from 220V is only 20 ms. In this case, the relay switches so quietly that the equipment can be located in the residential part of the house or cottage. The wall mount and fairly compact dimensions of the device (38.1 x 51.1 cm with a depth of 25.9 cm) will not take up much space even in a small hallway.
With a stabilization accuracy of 8%, this device reliably protects electronic devices by filtering noise and network interference. The correct sinusoidal current and even voltage serve as the basis for long and flawless operation of such expensive equipment as a gas boiler, refrigerator, washing machine or TV. Owners who chose Daewoo Power Products DW-TM12kVA were able to verify the reliability of the South Korean stabilizer during operation. Giving a positive assessment of this equipment in their reviews, users consider the more expensive cost of the device to be justified by its durability and quality of work.
1 Quattro Elementi Stabilia 12000
Another representative of the Quattro Elementi company, which has high performance characteristics and enjoys well-deserved popularity among users. As with the less powerful model, the Stabilia 12000 has the same key advantages - 98% efficiency, a wide range of operating mains voltage (140-270 V), the presence of three-level protection and a start-up delay (attached to the ability to connect asynchronous devices).
However, these are not the only advantages of a high-power stabilizer (the active power of which is 7.2 kW). With the increase in performance characteristics, there became a need for forced cooling of the device (which affects the increase in noise), equipping it with a Bypass function for energy transit when malfunctions occur (or exceeding the humidity threshold), as well as replacing sockets with more universal terminals. The disadvantages still include mediocre stabilization accuracy (about 8%), but with all the advantages and cost level, you can’t help but turn a blind eye to this. Moreover, the device shows excellent results in the general quality category.
How uninterruptible power supplies are connected
Voltage stabilizers for TVs are connected according to the general principle. No additional knowledge or skills are required for external devices. Most models have 5 connectors: input phase, neutral, ground zero, phase, going to the load point.
You can connect devices only when the power supply to the house is turned off. It is advisable to install an auxiliary RCD before the meter to extend the life of the uninterruptible power supply. A grounding loop is provided in the electrical network itself.
Important! You cannot monitor the stabilizer immediately in front of the counter. The optimal installation location is 0.5 meters from the TV, but not closer.
The connection diagram is simple - the stabilizer is plugged into an outlet. And the TV into the device socket marked “output”. The TV can only be turned on after all elements have been connected.
General instructions for choosing a stabilizer
A stabilizer is needed for all types of TVs if there are frequent voltage drops in the network, regular power outages occur, or the house has old wiring.
The selection and installation itself is carried out according to the following scheme:
- Decide whether to connect one TV or all devices to the stabilizer.
- The choice is to protect the entire network - install a backbone device, or just TV.
- Power outage in the house.
- Equipment installation.
- Starting the TV.
Electrical store employees can help you choose the right model. But for this they will need network parameters and the total power of the devices that will connect to the uninterruptible power supply.
