It happens that the voltage in the electrical grid jumps. This can lead to serious device damage. If you experience similar problems in your home, don’t forget to upgrade the voltage regulator for household appliances, such as.B. an LED TV, 8k TV.
Why do I need a stabilizer For LED Tv?
If you decide to purchase, first check to see if it is suitable for the device. This clarification is necessary because the main part of modern electronics, not only the TV, is equipped with a standard device to protect against overvoltages. But factory stabilizers Not designed for heavy loads and can only tolerate small falls. In the end, if you break devices, for example, the TV does not display the image, and there are significant power surges, it is not superfluous to install a stronger stabilizer instead of the regular one.
There are several subtypes of electrical stabilizers for television:
- Relay type system;
- servo motor or mechanical;
- Triac system;
- Voltage regulators with the possibility of double-conversion – can differ in their properties and their internal structure.
The most common because of its low cost is relay systems. They belong to the class of autotransformer stabilizers. Simply put, the conversion takes place at the output parallel to the conversion at the input. The system is maintenance-free. It can withstand a difference of fifteen percent.
The disadvantage may be resource limitations: The wear of the stabilizer is directly proportional to the frequency of jumps in the network. Among other things, the sound produced during operation is quite loud. Users who have already used a similar scheme do not supplement the model, but as a temporary option, it is quite suitable.
A higher position is held by the stabilizer, which provides better resources and properties for the relay circuit. This is a servo motor mechanism or an electromechanical stabilization circuit. The cost of the device can significantly exceed the systems of the previous generation, but they also exceed them by resistance level.
Of course, it was not without disadvantages. The servo motor mechanism is quite slow. If you prefer this subclass of stabilizers, you must attend the workshop regularly. Consumables – brushes – need to be replaced frequently, which can cause inconvenience.
In addition to the ones already described, the next voltage regulator has earned great popularity. The Triac system is prevalent in household appliances. This is a good stabilizer with a service life of three to five years. The scheme does not contain moving parts, which the designers were able to achieve quiet operation. Such a device does not require any special maintenance and is excellent at voltage equalization.
The heat can become a weak point of the stabilizer – thyristors usually fail due to too high heat. This type of outage causes network disruption.
Increased properties of the Triac stabilizer cause a significant price, but this is justified by a long service life and a high efficiency of 98%. Besides, the Triac stabilizers are the fastest, with a voltage peak reaction speed of 10 ms. High accuracy rates, immediate response to an emergency, a wide range of voltages, and all that, without another word, lets you choose such an effective device.
Stabilizers of this type are more effective than relay and mechanical systems. They work according to the principle of inverter devices. The decisive advantage is the possibility to convert alternating current into direct current and vice versa. By installing a special microprocessor in the circuit, high accuracy of currency conversion is achieved.
Such stabilizers are ideal for installation in devices with an output of 1 to 30 kW sensitive to voltage surges – these are LED TVs. They are durable (they work for up to 15 years), they are virtually silent, and they react quickly to emergencies.
Remember that buying one of the listed voltage equalization devices in household appliances is just reinsurance. Likely, it will never prove useful, and the money will be wasted. As already mentioned, most TVs are already equipped with regular voltage regulators. The purchase is only relevant for devices of the previous generation – tube or transistor models with the missing automatic voltage mechanism. Which of these – cheap or expensive – is to be chosen is up to you.
What you need to know when choosing a stabilizer
After all this, a logical question arises: How to choose a voltage stabilizer? Everything is straightforward. The first thing you need to pay attention to is stabilizing force.
It should be borne in mind that the rated voltage in the main part of our power grid is 190 V to 240 V. It is clear that jumps under such conditions significantly shorten the lifespan of televisions or computers. The drops of such power can irreparably damage the device and repair the smart TV itself quite heavily. Therefore, when purchasing a stabilizer, care must be taken to its throughput.
Also, the following indicators help to determine which system is better protected:
- Availability of short-circuit fuses;
- ergonomic case of the device;
- best pere boink with minimal noise during operation.
Also, such network devices can control several small devices, such as a stabilizer protecting the TV, computer system unit, and Internet modem.
How do you select the power and the corresponding wattage, which allows you to save while acquiring an effective stabilizer? This will help you especially marks on the body. They are equated with a certain kVA level. Anyone can calculate it: 1 kVA = 0.8 kW. After receiving information on the consumption of a particular group of electrical appliances (the approximate power consumption of different types of television sets can be determined from here), it will not be difficult to divide this power into kilovolts. These calculations will help you achieve the desired level of stabilization. The main thing is not to forget small errors usually. It is a kVA more than the specified.
All this should help in deciding whether a stabilizer is required for a TV. This is an essential protective device for last-generation devices that has not lost relevance today. Of course, someone can say that this is unnecessary insurance and a waste of money. However, it should not be forgotten that a stabilizer can function under favorable conditions for many years and saves your equipment at the most unexpected moment. And then you don’t have to think about why the TV stopped spinning or on and off itself.
