Do you need a voltage regulator for an LCD TV and which one is better to choose?

It happens, that the voltage in the electrical network jumps. This can lead to serious equipment breakdowns. If you have similar problems in your home, do not forget to stock up on voltage stabilizers for household devices, example, LCD TV.

Why do you need a stabilizer?

If you decide to buy, first of all clarify, will it fit the device?. Such a clarification is necessary because of that, that the main part of modern electronics, not only televisions, equipped with a standard device for protection against voltage surges. But the factory stabilizers are not designed for serious loads and can withstand only small drops. As a result, if your appliances break, example, the TV does not display a picture, and there are significant voltage drops, it will not be superfluous to take care of installing a more powerful stabilizer instead of the regular one.


There are several subtypes of electrical stabilizers for TV:

  • relay type system;
  • servo motor mechanism or mechanical;
  • seven-storage system;
  • voltage stabilizer with the possibility of double conversion - they can differ in properties and internal construction.

relay systems

Relay systems are the most common due to their low cost. They belong to the AUTO TRANSFORMER class of stabilizers. Simply put, the transformation at the output occurs in parallel with the transformation at the input. The system does not require maintenance. It can withstand a fifteen percent drop.

Limited resources can be a disadvantage: wear of the stabilizer is directly proportional to the frequency of jumps in the network. Among other things, sound, issued during operation, can be quite loud. Users, have already used a similar scheme, do not approve of this model, but as a temporary option it is quite suitable.

mechanical system

The stabilizer occupies a higher position, which has the resources and characteristics prevailing in the relay circuit. This is a servomotor mechanism, or whatever it is called, electromechanical stabilization scheme. The cost of the device can significantly exceed the previous generation systems, however, it also surpasses them in terms of resistance.

Of course, it was not without disadvantages. The servomotor mechanism works quite slowly. in addition, preferring this subclass of stabilizers, you will face the need to periodically visit the workshop. Consumable material - brushes - require frequent replacement, which may cause some inconvenience.

seven sided

In addition to those already described, this type of voltage stabilizers managed to gain more popularity. The triac system is quite common among the owners of household appliances. This is a good stabilizer, the period of operation of which is from three to five years. The scheme is deprived ??moving parts, which allowed designers to achieve silent operation. Such a device does not require special maintenance and perfectly copes with voltage equalization.

The weak point of the stabilizer can be high temperature - from excess heat, usually, thyristors fail. This type of failure causes interference in the network.

The increased characteristics of the three-storage stabilizer determine its considerable price, however, it is justified by a long service life and high efficiency — 98%. in addition, seven-storage stabilizers are the fastest, their speed of response to voltage surges is 10 ms. High accuracy rates, instant response to an emergency situation, a large range of incoming voltages, Needless to say, all this makes you choose such an effective device.

double transformation

Stabilizers of this type are more efficient than relay and mechanical systems. They work according to the principle of inverter devices. The key advantage is the ability to convert alternating current to direct current and vice versa. High accuracy of current conversion is achieved by installing a special microprocessor in the circuit.

Such stabilizers are ideal for installation in power equipment 1-30 kw, sensitive to voltage drops - this is exactly what LCD TVs are. They are durable (work up to 15 years), almost silent, quickly respond to emergency situations.

However, the cost of such devices is quite high: prices for individual copies can reach 60 thousand rubles.

Don't forget, that the purchase of each of the listed voltage equalization devices in household appliances is just reinsurance. It is likely, that you will never need it, and the money will be wasted. As mentioned earlier, most TVs are already equipped with regular voltage stabilizers. The purchase will be relevant only for devices of the previous generation — tube or transistor models with no auto-voltage mechanism. Which one to choose — cheap or expensive, only you can decide.

What you need to know when choosing a stabilizer

After all the above, a logical question arises: how to choose a voltage stabilization device? Everything is very simple. First of all, it is necessary to pay attention to the power of the stabilizing circuit.

It is necessary to consider, that in the main part of our power network, the standard voltage is considered to be from 190 In to 240 V. Needless to say, it is clear, that jumps under such conditions significantly shorten the service life of televisions or computers. Moreover, such power drops can irreparably damage the device, and it is quite difficult to repair the TV yourself. That is why, when buying a stabilizer, it is necessary to pay attention to its bandwidth.

in addition, determine which scheme will be better protected, the following indicators will help:

  • presence of short-circuit fuses;
  • ergonomic body of the device;
  • trouble-free with minimal noise during operation.

exept this, similar network devices are able to control several small appliances, example, one stabilizer protects the TV, computer system unit and Internet modem.

How power and the corresponding number of watts are selected, which allows you to save, but at the same time buy an effective stabilizer? Special markings on the case will help you with this. They are equated to a certain kVA level. Anyone can calculate it: 1 kVa = 0,8 kw. Having received information about that, what is the consumption of a certain group of electrical appliances (the approximate energy consumption of different types of TVs can be found here), a simple division of this amount of power into kilovolts will not cause any difficulty. These calculations will help you get the desired level of stabilization. The main thing is not to forget about a small error, usually, it is one kVa more than specified.

Everything described above should help in solving the problem, do you need a stabilizer for the TV?. This is a very important protection device for devices of the previous generation, which has not lost its relevance even today. Of course, someone might say, that this is unnecessary reinsurance and an unnecessary waste of money. However, do not forget, that is in favorable conditions, the stabilizer can work for many years and save your equipment at the most unexpected moment. And then you don't have to think, why your TV has stopped turning on or turns itself on and off.
