When the mains voltage in the house adversely affects the operation of the equipment, a stabilizer is needed. This will improve the functioning of devices, in addition, there will be no interruptions in electricity. Do I need a voltage stabilizer for an LCD TV? It is necessary for the normal operation of the device. About its purpose and types are described in the article.
The concept
Stabilizer - a device that allows you to balance the voltage. It serves as protection against surges with over or undervoltage to a normal level. In the case of intense changes, the devices are turned off, which is necessary to prevent burnout. Therefore, you definitely need a voltage stabilizer for the LCD TV.
But keep in mind that not all devices cope with this task, since many of them are configured for small loads. Therefore, when buying, you should remember about the power of the device. The voltage stabilizer for the LCD TV should be at 500-1000 watts.
LCD Information
This abbreviation refers to a liquid crystal display. That is why TVs are called “LCDs.” The technology for producing monitors is the use of liquid crystal molecules that respond to discharges of electrodes. As a result, they change the brightness and color when aligned in the direction of the electric field.
The image is obtained thanks to combined combinations in the mosaic order of the subpixels of the RGB triad. Many points allow you to create a video image that a person perceives a colorful "picture". Now these TVs are in demand due to high-quality images, excellent sound and other necessary characteristics.
Types of stabilizers
There are 4 types of voltage stabilizers for LCD TVs, which differ in structure, technical properties:
- Relay.
- Mechanical.
- Triac.
- With double conversion.
Each device has its own characteristics. To determine if a modern LCD TV needs a voltage stabilizer, you should determine how often voltage drops occur. If this is done regularly, equipment is required.
Relay
Relay devices are in demand because of the affordable price. They can withstand a 15% surge. The disadvantages include quick wear. And some relay devices are quite loud, so they should only be used temporarily. The approximate average price is 3000 rubles.
Mechanical
This type is much better than relay in all respects. But there are also disadvantages: the mechanical system functions rather slowly, and the brushes should be replaced only in the service. The average price of this type of device is 6000 rubles.
Triac
This type of device has earned positive reviews, as it has a long service life (3-5 years). Triac devices operate silently. In addition, they do not require constant maintenance. The downside is failure at high temperatures. The average cost is 10,000 rubles.
Double conversion
This voltage regulator for LCD TV will be the best choice, especially if the technique is modern. The device surpasses all the above systems in all respects. It is silent, durable, and also withstands large voltage drops. The price of the stabilizer is 35,000 rubles.
What to choose?
Many people prefer a triac stabilizer for an LCD TV. In this design there are no moving parts (brushes), it quickly equalizes the voltage. But we should not forget that the TV has an auto-voltage system. It is possible to establish whether there is a stabilizer in it, based on information from the data sheet.
It is important to check the quality of the electricity supplied to the house. It will be possible to determine the voltage fluctuations with the help of a tester, preferably a pointer, digital it does not show exactly. Even if everything is normal in this matter, you can buy a stabilizer.
The purchase of this protective device will allow you to save the TV, to prevent its breakdown. What could be a profitable acquisition that can protect against more expensive TV repair. What should be guided by when buying?
Criterias of choice
How to choose a voltage regulator for an LCD TV? When buying, you need to pay attention to the following nuances:
- Before purchasing, consult with a consultant.
- Choose the optimal power for the equipment.
- There must be a fuse that protects against short circuits.
- Ergonomics
- Noiselessness.
- Weight and parameters.
- The number of connections to the device.
If you purchase a reliable device, then it will prevent overvoltage. Then all the equipment will work fine.
Rating of available devices
Various voltage stabilizers for LCD TVs are sold. Which is better to choose? You can purchase equipment from inexpensive:
- Energy SNVT-1500 is a reliable Russian-made device. It functions automatically, so additional maintenance is not required. Created on the basis of modern technology, works with domestic electricity networks. The case is metal, and the power is 1.5 kVA (1 kW). The price is 4-6 thousand rubles.
- DefenderAVR iPOWER - a budget option, but still a quality relay mechanism. It is convenient to use, there is an electronic board. Equipped with a non-combustible fuse. Power is 1 kVA. The cost of 2 thousand rubles.
- Sven Neo R 600 - a device from Singapore manufacturer, has a compact design, weight is 1.5 kg. The mechanism is silent, the stabilizer is equipped with a digital display. The price is 3 thousand rubles.
- Uniel STR500 - a small device with two outlets, there is a display. Power is 0.5 kVA. Cost - 2000 rubles.
You can purchase a voltage stabilizer for the LCD TV at Eldorado or another hardware store. Even from inexpensive devices, you can choose a reliable option that will last a long time.
Where to install?
In the place where the device will be installed, the temperature regime indicated in the data sheet must be observed. For household single-phase devices, the minimum is +5 degrees. Three-phase can also work at negative temperatures up to -5. The maximum is +45 degrees.
During operation, heat is generated in the stabilizer. Its removal is provided by natural or forced ventilation. Between the body and the walls should be a space of not less than half a meter. The device is installed on the floor or on another surface - a table, a shelf.
There should be no carpet under the stabilizer, as this interferes with proper heat dissipation. The requirements for the absence of conductive dust and aggressive gases during operation are easily met. Another thing to consider is noise. Although some manufacturers guarantee that it will practically not be, it is advisable not to put the device in the bedroom. For this you need to use only non-residential rooms. The entrance hall or heated utility room is perfect.
Connection
Installation and commissioning must be carried out by a professional. A mandatory step is grounding. A copper wire is routed from the chassis to the ground bus. This is required to protect users from electric shock. An electromagnetic background harmful to humans is also reduced.
As a result, the equipment will be protected from breakdowns in the event of an accident. It also warns of impulse noise. In multi-unit and private houses, single-phase and three-phase devices are used.
Exploitation
After connecting the wires, the device is turned on. This will be indicated by a light indicator. Then the device will function automatically. If the light turns off at home, the stabilizer also does not work, and with its supply turns on.
The casing of the appliance cannot be protected from water ingress. Therefore, you do not need to put a container with liquid on it, for example, a cup of tea. Do not allow contact between the case and metal products. This is a safety requirement. If the ventilation is covered by something, then the stabilizer overheats, due to which it quickly breaks.
Another hazard is overload. It appears if a new equipment is connected, the power of which was not taken into account in the initial calculation. Therefore, before using new products, you need to check about the resolution of the total load. The user needs to regularly clean the dust from the appliance, but do not use wet rags and detergents. Repairs should only be carried out by a master in a service center.
Thus, the stabilizer is an important device in the house, where there are constant power surges. It is only necessary to choose a device of the appropriate power so that it runs smoothly. It is also important to maintain safety during operation.
