When buying technical equipment or household appliances, including televisions, sellers advise using them together with voltage stabilizers. The essence of their joint work is to extend the life and service conditions of the TV.
For many years, many consumers have not resorted to voltage stabilizers and their equipment works without interruption. But once the voltage inside the network goes beyond the permissible limit, as the equipment burns out.
In such cases, the question arises - do I need a stabilizer for the LCD TV?
What is a TV stabilizer and what does it do
TV Stabilizer - An electrical device for converting voltage. It has an input and output, which are designed to adjust the output voltage in a given range.
The stabilizer is a mediator between electrical appliances and the general electrical network of the house. It protects home appliances from breakdowns due to unstable voltage surges.
An unstable voltage value is applied to the stabilizer at the input. It can fluctuate or act irregularly. Inside the stabilizer, its value is transformed, and then changes within the required range. This ensures the safe operation of the mains and also protects devices from breakdowns due to power surges. At the output, the voltage is always equal to the specified parameters and is supplied to the appliance continuously at the required voltage.
Is it worth buying
Many new TV models already have built-in stabilizers, the so-called "auto voltage". They protect the electrical network from interference caused by the device itself. But it does not protect against common power surges.
All modern household appliances, especially new generation televisions, are equipped with switching power supplies. They continue to function over a wide range of input voltages. Their instructions for use indicate the amplitude of the voltage at which the device will not be damaged. Usually it varies from 110 to 250 units.
REFERENCE! If voltage is irregularly supplied to the outlet or its value is unstable, two variants of events should be expected.
The first is the input voltage is too low. If the voltage is too weak, the TV will simply turn off. An emergency shutdown will not entail any consequences. As soon as the voltage returns to the operating range, you can use the device again.
The second option is a voltage jump above the permissible value. This is the worst option. In such cases, a special element that is built into the TV input, the varistor, is damaged.
A varistor is a semiconductor resistor. Its operation and stability is completely dependent on the input voltage. A sharp surge in voltage above the desired level will lead to a short circuit.
When the varistor is damaged, the fuse blows and the TV circuit is deactivated. A damaged fuse can be replaced, and the circuit itself will autonomously come into operation after some time. But excessive overload inside the device each time will degrade its performance and productivity.
Pros and cons of such a purchase
The advantages of the stabilizer can be considered on the points:
- The entire power supply network will be controlled by a stabilizer and balance in the desired range - about 220 volts. All jumps and fluctuations will be smoothed, and at the output will be converted to a stable voltage.
- Safety and durability of the equipment. Many devices are sensitive to sudden changes in voltage. This leads to breakdowns and malfunctions. The stabilizer will prevent such emergencies.
- Acceptable price. Due to the affordable price, many consumers can afford to buy a stabilizer for the TV without sacrificing their wallet.
- Among the shortcomings can be identified the exactingness of the stabilizers to the operating conditions. They can only be installed in dry places that are protected from dust and moisture. Any such interference will quickly cause the device to malfunction.
The size of the stabilizer and its need for constant cooling can also add to the problems. The stronger the load on the device, the larger its dimensions and the more it will heat up. Proper cooling will protect it from malfunctions.
Despite the prudence of manufacturers and their attempts to secure the operation of devices, power surges can disable equipment. It remains for the consumer to decide whether to minimize the risks of equipment malfunction.
REFERENCE! There is a good alternative to voltage regulator. This UPS is an uninterruptible power supply. It protects the power supply network from interference and provides various technological devices with reliable continuous uniform power supply.
In the use of technology, you can do without a stabilizer, but any power surge beyond the working upper limit will lead to breakdown of all or individual parts of the device.
