Key features of network filters
Equipment of this class protects the load from short circuits, filters high-frequency interference, and protects against short-term voltage pulses.
When choosing a surge protector, consider the following:
- Number and type of sockets. Modern filters are equipped with from one to eight sockets. Connector C is a European standard with two pin holes. Type F is additionally equipped with grounding plates.
- Main parameters. This is, first of all, the maximum power and load current. If the total values of the equipment connected to the filter exceed the parameters declared by the manufacturer, you should select a model that can withstand higher loads.
- Protection systems. Modern surge protectors are equipped with protection against voltage surges and automatic shutdown in case of overload or overheating. Products of this type are also equipped with a high-frequency interference suppression circuit.
- Built-in switch. All surge protectors are equipped with a common switch installed on the top or side panel of the housing. Some models have individual toggle switches for each outlet.
- Length of cable. This parameter is related to the mobility of the product. A long cable is convenient in rooms with a large area. Adapter models without a power cord are suitable for local connection of electrical devices.
- Additional options. The presence of additional functions expands the capabilities of the device. Built-in light indicators inform you about the operation of the filter. Special loops or holes make it possible to mount the equipment on the wall. USB ports provide direct connection to gadgets for recharging.
How to connect a regular and built-in filter
A surge protector is often confused with a classic extension cord. The only common characteristics they have is their appearance. Their operating principle is different. The main task is to absorb voltage surges.
The connection is similar to turning on the adapter. Plug it into the socket, then connect the necessary household appliances to it. After the household appliances are connected, turn on the button on the housing. When used for more than seven days, it should be unplugged from the outlet during breaks.
Each model has its own maximum power rating for which it is designed. Therefore, it is important to ensure that the total load of connected devices does not exceed this value, otherwise the device will fail.
When working, you must follow the safety rules:
- You cannot connect several filters to each other;
- if a computer is connected to the filter, then you cannot connect fans, air conditioners and other powerful equipment to it;
- For equipment with high power, you should buy a separate filter.

Uninterruptible power supply (UPS)
In a specialized store, sellers may vie with each other to offer a stabilizer, a surge protector and a UPS. What is better to buy is difficult to decide right away given the existing large selection of models with different names and properties.
Many people purchase a UPS to eliminate one possible fault in the network - a sudden loss of voltage, in order to correctly shut down the operation of electronic devices. Imported models are designated UPS. It is advisable to purchase them with a stabilizer function to eliminate radio frequency and electromagnetic distortion and interference.
If the supply voltage disappears or decreases beyond the required range, the UPS switches to working through batteries. Depending on the model used, the operating time of an independent source can reach several minutes or hours. The device is selected according to the power of the equipment being protected.
An important characteristic of a UPS when operating on battery power is the output voltage shape. For cheap devices it is rectangular, and in frequency and amplitude it is equal to the mains sinusoidal voltage.

Stabilizer circuits
In a stabilizer, the voltage is regulated in different ways. One of them is switching the secondary windings of the transformer.
The voltage change is made by electronic keys controlled by the processor. Data comes from the sensor and is switched using an electronic switch on thyristors.
Parametric stabilizers use the phenomenon of avalanche breakdown on zener diodes, when the voltage remains constant despite a significant change in current. To amplify the power, the load is connected through one or more transistors.
Capacitors are used as high-frequency filters in the circuit. A stabilizer is a complex device that may include a surge protector.
The input resistor allows you to keep the transistor open and also maintains the zener diode in the active region.
The stabilizer is selected according to the power of the consumers. Nowadays, electronics are used everywhere, for example, in control units for energy-saving lamps. Therefore, it is needed not only for computers, but also for lighting systems. If it is used for electric motors, you should know that the starting current of the latter is several times higher than the rated current. Despite the fact that stabilizers allow short-term overloads, here a larger power reserve should be taken.
