Best voltage regulator in 2020

Some people believe that the voltage in the outlet is 220 V. However, in fact, this is not in all cases true. Even in the city there are drops in the network when the voltage drops by 10-20 V, albeit for a short time. This will not harm electrical devices, however, in some cases, an emergency occurs at substations, as a result of which the voltage will drop or, conversely, will almost double.

The voltage stabilizer is able to keep the devices connected to the network. All that remains is to choose a high-quality device that will help solve the problem and not break down in 2 years. To select the best voltage regulator in 2020, this rating was compiled.

Criterias of choice

Each house contains a large number of electrical appliances. And when some of them are unpretentious in the quality of electrical energy, some are afraid of significant voltage fluctuations. The question often arises as to which voltage regulator is better. To prevent expensive household appliances from breaking down, home owners buy similar devices. But not all products on the market can eliminate this problem. To date, the buyer is offered various designs that may differ in performance and cost. When selecting a quality home appliance, it is recommended to focus on the following characteristics:

• View. Structurally, devices can be relay, electromechanical, hybrid, electronic. In each of them, certain advantages and disadvantages are distinguished.
• Before going to the store, you should find out about the maximum voltage values ​​in the mains. Basically, there is a decrease to 90-140 V, but in some cases there are bursts of up to 270 V.
• Load. It is imperative to calculate what load will go to the stabilizer. For these purposes, it is necessary to summarize the power of any household appliances that are sensitive to voltage surges. Optimally, the power of the device is 20% higher than the obtained value. For example, for computers and televisions, the device power of 500-1000 W will be sufficient.
• Efficiency. The product in question consumes electricity, therefore it is important to establish the efficiency. The higher this parameter, the more efficiently household appliances will function and less electricity consumption.
• Accuracy. Consumers often have electrical equipment that requires voltage stability. In such a situation, experts recommend focusing on the accuracy of stabilization. This parameter indicates the error with which the voltage comes out of the stabilizer.
• Noise.When the device is connected to a refrigerator or boiler, it is assumed that the device will operate around the clock. Quiet operation will often come first, in particular when the device is located near a nursery or bedroom.
• The stabilizer is a stationary fixture, but heavy products are often troublesome for consumers. When you cannot hide it behind a curtain, then in this case you will need to choose a device based on the appearance.

To select a quality product, a list was compiled taking into account the opinions of experts and the characteristics of users. This rating includes the best voltage stabilizers for the home.
