Electrical appliances are powered from the network, and they need 220 V for high-quality operation. Unfortunately, this ideal is often unattainable, as volts in the network jump as they please. The quality of the devices is disturbed, and sometimes they even fail.
If your house has problems with the quality of the current in the network, this will invariably affect the operation of the compressor of the refrigerator - it will operate at increased or lowered speeds. And with a sudden jump in voltage, the electronics can even burn out. To protect electrical appliances from such undesirable consequences, voltage regulators are used.
To buy or not to buy - that is the question
If in doubt, do you need a stabilizer for the refrigerator, listen to the work of its compressor - if from it during the work emanates unusual noise, when you hear an excessive sound background, and the engine works with interruptions, it's time to think about purchasing a voltage regulator 220V for a refrigerator .
How to choose a stabilizer for a refrigerator?
Voltage stabilizers for the refrigerator are different. At a minimum, they differ in price. Cheap devices are usually manufactured in China, more expensive - Russian or Ukrainian production.
Often, Chinese trademarks are registered in other countries. To clearly recognize them, pay attention to the cost of the device. Chinese stabilizers are in the range of 2000 rubles. The capacity of such a stabilizer for a refrigerator is 1200-2000 VA. Expect from them a quality work is not worth it. They can be used only for inexpensive refrigerators.
Which stabilizer is better for a refrigerator?
If it is determined that the Chinese device does not suit us, then the next question arises: what kind of stabilizer is needed for the refrigerator to ensure the uninterrupted operation of the equipment?
Choose a domestic manufacturer, and the most attractive in terms of the ratio of "price-quality" are the following models
- Pskov stabilizers from the factory Progress 1500T, 2000T on thyristors;
- Tula models "Calm" R1200 or R2000, functioning on the relay;
- stabilizers SSC - the most optimal in terms of price and quality;
- high-precision R1200 SRT, 2000 SRT, working on triacs;
- stabilizers Lider RS1200W-30, W-50, PS2000 W-30 or W-50,
For industrial refrigerators that consume 380V, 3-phase stabilizers are needed. In this case, it is best to purchase the device from the Tula company "Shtil": models R3600-3, R6000-3 or R9000-3.
