The time spent by amateurs in the country, has long gone beyond the summer months. Many people with the onset of spring and late autumn prefer to live in the country, equipping it with the necessary electrical equipment: starting with an iron and a kettle, ending with welding machines and pumps. Given the quality of electricity supplied to the dacha-type villages, the electrical equipment in the country is at risk of being irretrievably damaged. We offer you to read the article “220V voltage stabilizer for questioning: how to choose a device to protect equipment”, the recommendations of which will help in choosing the best converter.
The need to connect a 220V voltage regulator to give
Most often in suburban and dacha settlements there is a reduced voltage in the network. This is explained by such circumstances:
- the use of low-power and old transformers that are not designed to service such a number of houses and a large load;
- the remoteness of suburban buildings from the characteristics of the analysis of electricity;
- simultaneous use of a large number of power tools and electrical appliances. In this situation, the main part of household appliances can not work in the correct mode, and sometimes it does not work at all.
Increasing the voltage in the network of holiday villages happens less frequently, however, it can lead to equipment breakdown or failure of individual blocks and elements.
If you stay in the country only occasionally, it will not save household appliances from a possible sharp drop in voltage and, as a result, its failure.
The only right decision in this case would be to purchase and install an acceptable voltage stabilizer for the dacha.
220V voltage stabilizer for giving: which one to choose (single phase or three phase)
The moments, which should be taken into account, intending to purchase a household voltage regulator for home and garden:
- house power supply system – single phase or three phase;
- total power of the existing electrical equipment;
- how much the planned stabilizer will be resistant to voltage drops, speed of response to oscillations and tolerance of overloads;
- the ability to operate the rectifier in a wide temperature range;
- the cost of the device and its reliability.
Usually in country houses and cottages there are single-phase power systems, but it happens that the owners provide themselves with three-phase power for the use of special electrical equipment. In accordance with the power supply system, voltage regulators are also selected: if the cable to the house contains two or three wires, a single-phase equalizer is needed, if there are four wires, a three-phase rectifier is required. In the case of a three-phase system, if the use of three-phase equipment is not planned, it is possible to connect three single-phase stabilizers.

The choice of single-phase voltage regulators for giving on the main parameters
Before proceeding with the analysis of various models of stabilizers, it is necessary to plan how the rectifier will work: whether it will be used for the entire system or be connected to some electrical equipment.
To determine the power of the planned stabilizer, you need to know the required rated power of the circuit breaker on the panel. If the machine is designed for 40A, then this figure should be multiplied by the existing voltage of 220V. The result is 8.8 kW. This figure and should be guided when choosing the power of the rectifier. In addition, it is recommended to choose a stabilizer with a certain power margin (approximately 20%). Hence, in our case, one should opt for a voltage regulator for giving 10 kW.
Helpful advice! The effectiveness of the stabilizer depends on the indicator of voltage deviation in the network. Strongly low voltage will contribute to lower efficiency of the device. Therefore, it is necessary to choose a stabilizer an order of magnitude greater in power from the calculated power value of the instruments.
Of course, quite powerful rectifier models are notable for their high cost. In order to more accurate calculation, you can sum up the power of all located at the cottage electrical equipment and technology. However, one should not forget that the starting power of the equipment, which has electrical equipment in its device, will increase by 3-5 times. These indicators must be considered when determining the capacity of the equipment.
You can also connect via the stabilizer only certain appliances at your discretion, for example, only a refrigerator and air conditioning. Then it would be enough to purchase a voltage equalizer with a power of 3 kW. This voltage regulator 220V to give the price will be much lower.
The criteria for selecting voltage equalizers for country houses are based on the fact that most often the country house is used occasionally. As a result, the country house is not heated in winter, and the electricity supply at such sites is obviously poor quality. In such a case, such characteristics of the devices as operability at negative temperatures and the possibility of voltage stabilization in a wide range will be important.
Stabilizers to give should have a sufficient input voltage range, especially with regard to the lower limit. This is necessary so that at reduced voltage or switching on powerful equipment, other equipment in the house does not turn off. In addition, when operating household appliances in dacha conditions, a rectifier is needed that is capable of operating in overload and low temperature conditions, which is smoothly regulated and silently operated. After all, often country houses are equipped with different types of equipment, including high-precision electronic control, which requires high-quality protection.
To choose the right stabilizer, you need to follow what is the maximum and minimum voltage in the network. Depends on this, with what range of conversion will have to install the device.
Helpful advice! For a daily measurement of the range of voltage fluctuations in the network, use a voltmeter or a fine meter.
You should also pay attention when buying on the accuracy of voltage equalization. If you are offered to purchase a device with a precision adjustment of 10%, then this figure is not one of the best and will not always be able to protect high-precision equipment. You should opt for models with an accuracy of 1% to 5%.
A large role is played by the duration of the voltage drops. In this case, the stabilizer must have the ability to work in conditions of overload.
If you plan to use a rectifier in winter, you should select models with the ability to operate at low temperatures.
Thinking about how to choose a voltage regulator 220V for villas and cottages, you should pay attention to how to install the device. Manufacturers offer a floor installation method and wall mounting option. Considering that country houses, as a rule, are not distinguished by weighty dimensions, and square meters of space are strictly distributed, it would be ideal to install a wall voltage converter.
Wall rectifiers have a modern design, do not clutter up the room and have a number of qualities to protect electrical engineering in the country.
Wall-mounted voltage converters are installed in the area after the electric meter. All that is required for its installation is to fix the mounting plate on the wall and hang the device on it.
Wall-mounted stabilizers are reliable in operation, their use in the country will allow you to be confident in the energy saving of household appliances, electric boilers, pumps and power tools. An important feature of wall analogs is that they can be mounted in utility unheated premises and function in different temperature conditions, which is especially convenient for country houses and cottages.
The main characteristics and cost of the stabilizer depend on the type and device of the device. When choosing, first of all you should take into account individual needs. There are three types of rectifiers on the electrical equipment market, the distinguishing characteristics of which are given below.
Relay devices. The choice of the stabilizer to the country for many is determined by the cost of the device. From this point of view, a relay voltage rectifier is a current variant. This device has a good equalization speed and a sufficient input voltage range. User feedback indicates a long service life of relay stabilizers, their ability to withstand long-term overloads (over 100%). The disadvantages include the accuracy of output indicators up to 7%.
Helpful advice! If your house in the country has a high-precision equipment that is sensitive to minor voltage fluctuations, you should choose a stabilizer with an alignment accuracy of less than 3%.
Electromechanical stabilizers. Such devices incorporate 2-3 transformers, have sufficient power and reasonable price. Users consider the advantages of these devices: accurate indicators of output voltage, smooth regulation, insignificant sensitivity to oscillations, silent operation. Electromechanical rectifiers carry a brief overload up to 200%. Electrodynamic transducers capable of operating at low negative temperatures down to -20 ° C and withstanding short-term overload (2 min) up to 200% belong to this type of stabilizer, but their price is much higher.
Electromagnetic Rectifiers. These devices are perfect for work in summer houses located in a zone with harsh climatic conditions. They easily cope with their functions at low (up to -40 ° C) and high (up to + 50 ° C) temperatures, endowed with a high stabilization rate. From the reviews it is known that electromagnetic transducers are noisy, so it will be important for them to choose a place outside the living rooms. In addition, they are sensitive to changes in frequency and stop their work when the load decreases by 15%. This should be considered when choosing devices for holiday villages, where the voltage surges are quite large.
The correct choice of a voltage stabilizer for giving will guarantee uninterrupted power supply of electrical equipment and will extend the life of the existing equipment.
