What is a voltage stabilizer for a TV and why is it needed and is it for all TV models? For the TV to work, it is necessary to provide the necessary power supply parameters. The nominal value of the voltage in the network is 220 V, but in practice it may vary slightly. The TV works on the assumption that the voltage is approximately equal to this value. If it is very small or significantly more than 220 V, this may lead to the inoperability of the equipment or its breakdown.

GOST considers such situations. Usually it is enough that the deviations do not exceed 10% of 220 V. If the voltage does not go beyond these limits, then viewers can safely watch television programs.

In real life, accidental shutdowns or other emergencies cannot be ruled out. In some cases, a surge may occur, which will lead to a voltage increase above 300 V. Such situations are usually beyond the control of the owner of the equipment. To eliminate their occurrence, it is enough to use a voltage stabilizer.

Why you need a stabilizer to protect your TV

The stabilizer is a device that is connected to the mains. The TV plug is included in this appliance. As long as the voltage remains normal, it is supplied unchanged to the power cable of the TV. As soon as it becomes too small or large, it is blocked, and instead it remains normal at the output. If the electricity suddenly disappears, then after a few minutes the transformer turns off. There are various types of such devices with various useful features. You need to choose the one that best suits the owner of the TV, taking into account the peculiarities of his situation.

Does everyone need a TV stabilizer

Stabilizers reliably protect TVs from sudden power surges. However, technology is constantly evolving and in new models, manufacturers are trying to protect their equipment to a greater extent. Therefore, sometimes there is an opinion that the use of stabilizers has lost its relevance.

The operating voltage range is indicated on the back of modern TVs [/ caption] New TV models use switching power supplies. One of their features is that they continue to work well even with a significant voltage deviation from the nominal. In most cases, they work well in the range from 100 to 250 V. In a significant number of cases, this saves the situation. These units may have a fuse installed that will melt if the voltage rises sharply, but this facility is usually a one-time use. However, occasionally more serious failures can occur. This applies to sudden shutdowns or various kinds of emergencies. For example, if the neutral wire breaks in the network, the voltage in the outlet can sometimes reach 380 V. Switching power supplies will not be able to save from such situations. Those who live in rural areas are usually more likely to experience power surges. If they are strong enough, then it can threaten to break. In order to more accurately find out the capabilities of the TV model you are buying during power surges, you need to check this information with the seller and read the instruction manual. When buying, you need to take into account the degree of reliability of the power supply used in the apartment or house.
Why do you need a voltage stabilizer for a TV and how to choose itSome TV manufacturers produce branded devices for voltage stabilization. Among them, for example, is LG. However, their cost is relatively high. If the network is unreliable, and power surges occur regularly, then the purchase of a stabilizer is necessary. In cases where the network is stable for many years, you can refrain from buying such a device. The user must choose which category to classify their situation into.

What types of stabilizers are used

The types of stabilizers are as follows:

  1. Relay stabilizers are the most affordable. They allow a deviation of 10% from the rated voltage at the output. For some TVs, this may not be enough. The operation of the device is based on the use of a stepped winding transformer. With sudden voltage changes, the controller switches between them. Sometimes the number of steps is too small and does not provide a sufficiently smooth shift.Why do you need a voltage stabilizer for a TV and how to choose it
  2. A servomotor or, as it is also called, a mechanical device has higher reliability and quality compared to a relay one. However, it has a higher cost. In order for it to work well, it needs regular maintenance. When changing, the brushes move along the turns of the transformer wire. At the same time, there is a fairly high quality, but the speed remains insufficient. Such devices work well only in heated rooms.
  3. Even better are triac or thyristor devices . In the event of failures, the device is able to quickly equalize the output voltage. A critical problem can be a strong overheating of the stabilizer. It can lead to its burnout and inoperability. It has a relatively high price. In some cases, interference may occur from it. However, these devices have a long service life.
  4. Double conversion models , despite their relatively high cost, are the best choice. Such transformers have the largest input voltage range at which its stabilization is available. This technique has been working efficiently and reliably for many years.

When choosing, the owner of the TV must take into account the quality of the electrical network and the available financial opportunities.

Specifications

Stabilizers are selected taking into account their technical characteristics. They are as follows:

  1. The power must exceed the corresponding characteristic of the connected appliance.
  2. The stabilization accuracy characterizes the maximum deviation at the output from the rated voltage.
  3. It should be borne in mind that some devices are noisy and may cause discomfort to the audience during operation.
  4. The allowable input voltage range means that the desired voltage will be output for the indicators inside it. When out of bounds, the TV will be turned off.
  5. Design and dimensions must be taken into account in order to choose a device that will match the design of the room.
  6. High speed will allow you to better respond to power surges.

Choosing the right device will allow you to use it for many years.

Parameters to pay attention to when choosing

Stabilizers produced by the industry are designed for use in various conditions, depending on their technical characteristics. When buying, you need to carefully read them and pay attention to the following:

  1. Power supply networks are single-phase and three-phase . The purchased device must comply with this. For single-phase networks, it must be single-phase. Three-phase stabilizing devices are more often used for industrial purposes. If there is such a network at home and there are powerful electrical appliances, then it makes sense to install them at home. Sometimes three single-phase devices are installed instead.
  2. The power of the stabilizer must correspond to this parameter for the television receiver. In most cases, this indicator is in the range from 300 to 1000 watts. It is generally believed that the power of the stabilizer should be at least 30% more than the power of the TV.
  3. The stabilizer is actually a piece of furniture, as it will stand next to the TV. Therefore, it is necessary to consider how it will fit into the home environment .

How to connect a stabilizer to a TV

The procedure for connecting the stabilizer must be carried out correctly – it is not difficult to do it yourself. To connect, you need to take the following steps:

  1. Before you start the procedure, you need to turn off the electricity in the apartment or house, and then install an RCD at the entrance to the power grid. This measure will be able to provide protection for electrical appliances in the most dangerous situations.
  2. The electrical network must be provided with grounding.
  3. The stabilizer is installed next to the TV.
  4. The stabilizer is connected to an outlet, connected to ground and a TV is connected to it.

After that, you can start watching TV.

How to understand that the stabilizer is out of order

Although the devices in question are reliable, one must be prepared for the fact that they may have malfunctions. The most common are the following:

  1. The noise during operation is higher than usual, the presence of loud crackles and clicks.
  2. Turns off when under load. This usually happens when it exceeds the usual indicators.
  3. The output voltage cannot be obtained. In each type of stabilizer, this can be caused by different reasons. For example, in a mechanical one, this occurs when the brushes are worn out and their contact is incomplete.
  4. If stabilization occurs in abrupt steps, a faulty switch is usually the cause. In mechanical devices, lack of lubrication may be an additional cause.

If the device does not show signs of life, it can be taken to a workshop for diagnostics and repair.

Repair and replacement

If malfunctions are found, you can disassemble the device and check inside for burning and damage. If problems are found, you can rewind the transformer or replace it with a more powerful one. If it is difficult to carry out repairs yourself, it makes sense to contact specialists. In this case, it is important to compare the cost of repair and purchase of a new device. Sometimes the latter option is more beneficial.
