Despite its impressive dimensions, the refrigerator is a sensitive household appliance. Its serviceability depends on the supply of electricity, and in the city, as you know, this often causes problems. As a result, service centers do not remain without work and every day, hundreds, "reanimate" refrigeration units. Is it possible to protect household appliances from “surges” in the network? Sure! A voltage regulator will help you with this. Now let's figure out how to choose the right voltage regulator for the refrigerator.

Why do you need a voltage regulator?

Why do you need a voltage regulator

Regardless of the coolness of the brand and type, all refrigerators are powered from the mains. But we know perfectly well what a disgusting quality the current "walks" through the electric networks and highways. And every day its quality is getting worse and worse.

The main reason for constant voltage drops is the congestion of networks, which has long exceeded the permissible limits. But for a refrigeration unit, it is not the voltage itself that is dangerous, but a "jump", that is, the period of time between turning off and turning on. Imagine turning on the refrigerator requires twice the power (nominal) than indicated in its passport.

The most vulnerable part of the refrigerator is the compressor, or rather the board located on it, which is "responsible" for the "cold reproduction". Just think, repairing it will cost you at least half the cost of the unit itself. How to avoid unwanted damage? Install a voltage regulator.

Of course, you can say that you have the latest generation "frost giant" in your home with built-in security features, and you don't need any additional equipment. You may not need it, but it will not hurt the refrigerator.

Remember, the built-in voltage regulator (if there is one, of course) does not pull the protection of the refrigerator due to low power. So all these "loud statements" are nothing more than a simple marketing ploy to increase sales and raise the reputation of a particular brand. In practice, it has been proven that any refrigerator must be connected to the network through additional protection systems. Otherwise, it will not even serve you the warranty period.

How to choose a voltage regulator

You came to the store. How do you plan to choose a voltage regulator for your refrigerator? Do not know? Then listen carefully. The most common mistake people make is buying security devices based on the brand and the high cost. Like, more expensive is better. A well-known brand will never "put a pig on it" ...

Forget it once and for all. Today, price is not an indicator of quality. And by the way, the name of the manufacturer too. And put the appearance of the device immediately into the background, "in people" with it you will not go out.What should you pay attention to when choosing a stabilizer?

One phase or three?

For your refrigerator, a stabilizer is protection. But what it will be, the second question. Today, single-three-phase stabilizers are very popular.

A single-phase stabilizer will "pull" only a refrigerator, a three-phase one can protect several household appliances at once. Before making your final choice, be sure to weigh the pros and cons. Think about whether your home still has “serious” household appliances that need protection from power surges. If one is not available, it is enough to get by with a single-phase device.

Moreover, consumer home power grids often have only one phase, so buying a three-phase stabilizer, which is several times more expensive, simply does not make sense.

The most important criterion is power

The most important indicator of the unit's performance is its capacity. It should be 20% higher than the capacity of the refrigerator itself. If the device has to "pull" any more household appliances, you need to calculate the total power of all connected appliances and add 20% of the total amount you received.

It is not difficult to find a 220V voltage stabilizer for a household refrigerator. And calculate the required parameters too. And there is no need to be a great mathematician for this. Moreover, the manufacturer took care of you in advance, and took over all the calculations. The main thing is to know the power of your refrigeration unit (it is in the passport). And based on this data, buy an inexpensive but effective stabilizer.

Stabilizer types

Voltage stabilizers are:

Electromechanical. Such devices are used only where voltage drops are the exception rather than the rule. The input and output voltage is regulated electronically.

Advantages: high accuracy.

Disadvantages: low voltage conversion rate.

Triac... An expensive pleasure with a lot of advantages, which is controlled by means of adjusting levers with proximity switches.

Relay. The power is regulated by relay switches activated by electrical impulses.

Whether you need a stabilizer is up to you, of course. But do not forget that buying it is an investment that will save you from troubles and big expenses in the future.

Each room has its own stabilizer

A stabilizer bought for an apartment is not suitable for a summer residence. Suburban equipment is mainly equipped with an asynchronous "insidious" motor. No, the engine itself is not terrible. Its launch is scary. So in order to put into operation any pump with a capacity of 1.3 kW, you need twice as much power, that is, 2.6 kW.

Therefore, choosing a power stabilizer for a summer residence, you need to find the sum of all household items that will be connected to the device and add another 45% of the result to it. Believe me, here it is better to choose more, in order to surely protect your household appliances or breakdowns.

It is easier with "home" stabilizers. Especially if you are planning to buy a device exclusively for the refrigerator. Well, if you own a private house, when connecting the stabilizer, you also need to take into account the phase of the network.

It is easy to measure using special devices that plug into an outlet. Analyze the data, find errors, measure the power of all household appliances and go shopping. And don't forget to keep this article in case you forget how to choose the right 220v voltage regulator for your refrigerator.
