Volt voltage stabilizer rating

Among the variety of manufacturers it is very difficult to choose the voltage regulator that is best suited for the task. One is good for installation in the country, the other for the refrigerator, the third is ideal for the boiler, the list goes on. In my review, I want to highlight the most popular models on the Russian market and find among them the best in terms of price and quality.

It makes no sense to compare all brands, as most of them are manufactured at the same factory, but under a different brand. Therefore, the following popular brands will participate in the review:

1. Leader (Russia, Pskov)
2. Volt Engineering (Russia, Moscow)
3. Rucelf (China)
4. Energotech (Russia, Taganrog)
5. Energy (Russia, Moscow)
6. Resanta (China)
7. Progress (Russia, Pskov)

When comparing certain models, the principle of selection for the widest range of operation and stabilization was used, which is usually one of the most frequent selection criteria after the price.

Operation thresholds

The range of operation shows the boundary values ​​of the input voltage at which the device will disconnect the load. The boundaries of the input voltage at which the product will output the declared 220V as a rule are significantly narrower than the trip thresholds.

It is worth noting that not all manufacturers indicate these thresholds in the description of the device characteristics, thereby misleading the buyer.

Stabilization accuracy

This parameter is important for high-precision equipment, it shows how much the voltage after the device will differ from 220V. According to GOST, the deviation of ± 10% is permissible for the normal functioning of most equipment.

Built-in protection

Any stabilizer, in addition to its main function of maintaining the output voltage within 220V, should also have a number of protective functions that will help protect both household appliances and the product itself from malfunction. Below is a list of features that are declared by the manufacturer.

Overall dimensions, weight, type of placement

Often, the selection of a stabilizer rests on its dimensions, which is especially true for rooms with limited space for the installation of this product. Wall-mounted installation makes it possible to place the product even in the most cramped conditions, and the floor is more in demand when it is impossible to hang on the wall.

Bypass mode ("transit")

Bypass mode is designed to connect the load bypassing the stabilizer in case of problems with it, or if necessary, start a high-power load, which is not recommended to be switched on through the adjustment circuit. Distinguish between mechanical and electronic transit. At the first, the voltage from the network is directly transferred to the load without any protection. With an electronic product, it passes voltage without stabilization, but at critically low or high values ​​it disconnects the load, i.e. performs the function of a relay.

Additional functions and information display

A clear and informative indication allows you to make the stabilizer interface more accessible to an unprepared user. An oversupply of data will only confuse, and a lack of data will complicate the understanding of certain features of the device.

Price, Warranty

After reviewing all the features of the stabilizer and choosing the most suitable one for the parameters, it often turns out that it costs a lot of money or, on the contrary, a very expensive brand presents few opportunities, is poor in functionality and has a small guarantee.

The result of this review is a summary table with an overall rating of the best model and for a separate parameter. The highest score is 8, and the lowest is 1.If the significance of a function is unambiguously difficult to evaluate, then products are given the same average score of 4.

As can be seen from the results, the top three stabilizers in terms of total score included the Volt Engineering models Amper-R E 16-1-25 V2.0 and Hybrid E 9-1-25 V2.0, as well as the model of Energotech OPTIMUM -5000.
