Do I need a voltage regulator for an LCD TV?
When the mains voltage in the house is negativeaffects the operation of machinery, a stabilizer is needed. This will improve the functioning of the devices, besides there will be no interruptions in electricity. Do I need a voltage regulator for an LCD TV? It is necessary for normal operation of the device. About his appointment and kinds is told in the article.
The concept of
Stabilizer is a device that allowscounterbalance the tension. It serves as a surge protection against exceeding or lowering the voltage to a normal level. In the case of intensive fluctuations, the devices are switched off, which is necessary to prevent burnout. Therefore, you definitely need a voltage regulator LCD TV.
But it must be taken into account that not all devicescope with this task, since many of them are configured for small loads. Therefore, when buying, remember the power of the device. The voltage stabilizer for the LCD TV should be 500-1000W.
About LCD
This abbreviation indicatesliquid crystal display. That's why TVs are called LCDs. The technology of obtaining monitors is the use of liquid crystal molecules that react 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 combinedcombinations in the order of mosaic subpixels of the RGB-triad. A lot of points allow creating a video image that a person perceives with a colorful "picture". Now these TVs are in demand because of the high-quality image, excellent sound and other necessary characteristics.
Types of stabilizers
There are 4 types of voltage regulators for LCD TVs, differing in structure, technical properties:
- Relay.
- Mechanical.
- Triac.
- With double conversion.
Each device has its own characteristics. To determine whether a modern LCD TV requires a voltage regulator, you should determine how often voltage drops occur. If this is done on a regular basis, equipment is mandatory.
Relay
Relay devices are in demand due to the availableprices. They can withstand a 15% surge in voltage. The shortcomings include fast wear. And some relay devices are quite loud, so they should be used only temporarily. The approximate average price is 3000 rubles.
Mechanical
This type is much better than the relay one in allcharacteristics. But there are also disadvantages: the mechanical system is rather slowly functioning, and the brushes should be replaced only in the service. The average price for this type of device is 6,000 rubles.
Triac
This type of device has received positive reviews,since it has a long service life (3-5 years). The triac does not operate silently. In addition, they do not require constant maintenance. A disadvantage is a failure at a high temperature. The average cost is 10,000 rubles.
Double conversion
This voltage regulator for LCD TVwill be the best choice, especially if the technique is of a modern kind. The device is superior in all respects to all of the above systems. It is noiseless, 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 forLCD TV. In this design there are no moving parts (brushes), it quickly equalizes the voltage. But do not forget that the TV has an auto-voltage system. It is possible to determine whether there is a stabilizer in it on the basis of the information of the technical passport.
It is important to check the quality of electricity,arriving at home. Determine the voltage fluctuations will be obtained with a tester, preferably a switch, digital does not exactly indicate this. Even if everything is fine in this matter, you can buy an auto stabilizer.
The acquisition of this protective device will allowkeep the TV, do not let it break. What can prove to be an advantageous acquisition, able to protect against more expensive TV repair. What should I do 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 buying, consult a consultant.
- Select the optimal power for the equipment.
- There must be a fuse that protects against short circuits.
- Ergonomics.
- Noiselessness.
- Weight and parameters.
- Number of connections to the device.
If you buy a reliable device, then it will prevent overvoltage. Then all the equipment will work fine.
Rating of available devices
Various voltage regulators for LCD TVs are sold. Which is better to choose? You can buy equipment from inexpensive:
- Energy SNVT-1500 - reliable device of Russian production. It works automatically, so no additional maintenance is required. It is based on modern technologies, works with domestic power 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. They are convenient to use, there is an electronic display. Equipped with a non-combustible fuse. The power is 1 kVA. The cost of 2 thousand rubles.
- Sven Neo R 600 - the device of the Singaporemanufacturer, has a compact design, the weight is 1.5 kg. The operation of the mechanism is noiseless, the stabilizer is equipped with a digital display. The price is 3 thousand rubles.
- Uniel STR500 - a small device with two sockets, there is a display. The power is 0.5 kVA. The cost is 2000 rubles.
You can buy a voltage regulator for LCD TV in "Eldorado" or other equipment 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,Observe the temperature conditions indicated in the data sheet. For household single-phase devices, the minimum is +5 degrees. Three-phase ones can work also at a negative temperature down to -5. The maximum is +45 degrees.
During operation in the stabilizer,heat. Its withdrawal is provided by natural or forced ventilation. Between the shell 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.
Under the stabilizer there should be no carpet,Because this violates the correct heat removal. Requirements for the absence of conductive dust and corrosive gases during operation are easily met. One more thing to consider is noise. Although some manufacturers guarantee that it will not be practically there, it is advisable not to place the device in the bedroom. To do this, use only non-residential rooms. Perfectly suitable entrance or heated utility room.
Connectivity
Installation and commissioning shouldperformed by a professional. An obligatory stage is grounding. The copper wire is routed to the ground bus from the housing. This is required to protect users from electric shock. It also reduces the electromagnetic background, which is harmful to humans.
As a result, the technique will be protected from breakdowns in case of accidents. It also warns about impulse noise. Single-phase and three-phase devices are used in multi-family and private houses.
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 lights turn off at home, the stabilizer does not work either, but turns on with its supply.
The body of the device does not protect against penetration of waterinside. Therefore, it does not need to put a container with liquid, for example, a cup of tea. Do not allow the housing and metal products to contact. This is a security requirement. If the ventilation is covered by something, the stabilizer overheats, which causes it to break quickly.
Another danger is overload. It appears when a new technique is connected, the power of which was not taken into account in the initial calculation. Therefore, before using the novelties, it is necessary to check the total load resolution. The user needs to regularly wipe the dust from the device, but do not use a wet rag and detergent. Repair should only be performed by a service technician.
Thus, the stabilizer is importantdevice in the house, where there are constant voltage surges. It is only necessary to choose a suitable power device in order to work smoothly. It is also important to observe safety during operation.
