Why do some sellers recommend buying a voltage stabilizer when buying a TV? How to choose this unit, and is it so necessary? Abrupt blackout and voltage drops are an unpleasant thing, but often found. Horse racing most often happens:

  • when cable breaks;
  • when using powerful equipment (for example, a welding machine for construction);
  • temporary power outage.

Do power surges affect household appliances?

Of course, small fluctuations cannot have a special effect on the state and condition of the equipment. But if we are talking about a sharp power surge, then this phenomenon can damage the power supply of the TV and the device itself. In this case, it is better to secure it by connecting a stabilizer.

What is a voltage regulator?

This is a special device designed to analyze the indicators of the incoming voltage and equalize it, if necessary, up or down converting it to standard 220V.

By the principle of action, stabilizers are:

  1. Relay. Units of transformer type, which are capable of converting indicators at small jumps. With a high voltage drop, the device itself often fails. As a rule, such devices have a low cost.
  2. Electromechanical or servo-drives for equalizing voltage indicators. These devices are able to equalize jumps of a small range, while the speed of such a device is also low. They differ from the first type of models in compact dimensions and a slightly longer service life.
  3. Stabilizers with electronic control system. As a rule, models of this type of units are the most expensive, but provide excellent speed and are able to equalize voltage indicators with large deviations from the norm of 220V.

Voltage regulation devices for different types of TVs

Some buyers mistakenly believe that if you choose a voltage stabilizer for LCD TVs, then it can not be used, for example, for a plasma receiver. This is actually not the case. Regulators are universal units capable of connecting to any type of equipment, including any type of television. Any of the representatives of the devices, for regulating the indicators of current intensity, can be used to connect to any TV. The choice of the type of controller depends only on the power of the TV. So, for various stereo systems and home theaters you will need a more powerful unit than for a conventional TV. At the same time, there are special models of such devices from the manufacturers Phillips, LG, Samsung themselves, but often they have a cost significantly higher than the cost of a conventional stabilizer.

What to look for when choosing a stabilizer?

In order for the purchase of an additional device to be justified, and the stabilizer to serve for a long time, it is necessary to take into account some points:

  1. Determine how much you need to purchase such a device. If the jumps in current intensity are small or occur extremely rarely, then some power supplies are quite capable of withstanding them. In this case, you can do with the protective system of the unit itself.
  2. It is advisable to look for a device with the additional possibility of protection against short circuits and a system for cleaning the network from interference.
  3. Dimensions of the device.
  4. Ways to connect to a network and devices.
  5. Noise level at work.
  6. Device power. One of the important indicators, since if the power of the control device is less than the indicator of the TV, then the meaning of this purchase will be reduced to zero.Therefore, before choosing a stabilizer, you need to see what the power of the TV is. Typically, such information is indicated in the technical passport or on the back of the case. Based on the power indicator of the TV or its power supply, it is necessary to choose a stabilizer that has more power.
  7. The number of connected representatives of the equipment and their total power value. In order to connect the regulation system to several devices, it is necessary to summarize the power indicators of all devices and select a voltage regulator based on these data.

DefenderAVRInitial 1000 Series

Overview of regulator models and their characteristics

This review presents models of inexpensive devices costing from 1,500 - 6,000 rubles.

  1. DefenderAVRInitial 1000 series. Inexpensive automatic regulator with a power of 320 watts. It is equipped with a system of protection against overheating and overloads, as well as a built-in surge protector. Compact device with an indicator of the current network status.
  2. DefenderAVR model iPOWER Medium-sized electronic device with a power of 300 watts. Provides high speed, silent.
  3. SvenNeo R 600. The stabilizer is able to convert the current intensity to 220V at an input value from 150 to 280V. The device is equipped with an additional high-frequency interference filtering function. What is especially important for sensitive devices such as televisions. This device automatically shuts off when overloaded, overheated, or short-circuited.
  4. Uniel STR500 300 watts. Convenient and compact controller with a maximum power of 300 watts. Able to equalize the current intensity indicators in the network from 145 to 280V at the input. Equipped with an indicator that shows the status of the operating voltage and overload.

It should be noted that the acquisition of regulators for each individual type of equipment is not advisable. Therefore, to provide protection against changes in all household appliances in the house, it is better to purchase a more powerful wall stabilizer. Such devices are characterized by high power (about 8000 watts) and are able to withstand significant voltage and load drops.

If we are only talking about protecting an expensive TV or home theater, then in this case it is better to purchase a special small power regulator which will be enough for one device. Some television receivers have built-in stabilizers, but the power supplies of modern TVs are unable to fully protect the device from sudden and significant power surges. Therefore, the purchase of a stabilizer may significantly extend the life of the device.
