Voltage regulators are designed to automatically maintain the specified power supply voltage (220/380). Functionally, provide: the full protection of electrical and electronic equipment for household and industrial use by the sudden change in voltage supply, stable power equipment in the permanent under-or over voltage power supply; Opportunity fail-safe and correct operation of electrical equipment in an unstable mains, control voltage at the input and output, filtering line noise and distortion; Automatic adjustment output voltage with high .V depending on the power supply and load connected voltage regulators are divided into single-phase and three phase, depending on the principle of action – on electromechanical and electronic. Voltage srm relate to the type of electromechanical voltage regulators, for which, in contrast to the electron-type stabilizers, is characterized by smooth automatic regulation of output voltage with high accuracy to maintain, they have great overload capacity and low noise. How to choose a stabilizer order to determine the choice of voltage stabilizer, one must first answer the following questions. What is needed voltage – single phase or three phase? With single-phase mains (220V), questions arise. In the case of three-phase network (380) are possible options. If you have a three-phase network has at least one three-phase consumer, you must install the three-phase voltage regulator. If all consumers are single-phase, in most cases, better pick up three single-phase stabilizer.

As a rule, it is cheaper. But there is one major advantage. This option allows you to bypass the feature of three-phase stabilizers, namely, the disconnection of the device if power fails at one of the phases. Do I need to put some voltage to different consumers, or better put one at all? If you need to protect a specific electrical loads, will be enough of a stabilizer of appropriate power. If you want to secure the maximum number of appliances, then you can certainly put on each device its own, separate regulator, but practically it is not convenient, and financially – is not beneficial. In this case, it would be better to establish a common voltage to all consumers.

Although there are other options. For example, to allocate a certain group appliances that are most critical of the surges. What power is required voltage? For proper model selection, voltage regulation is necessary to determine the amount of power (W) all customers who need both in the supply of electricity. When calculating the power consumed by the device should take into account the so-called full capacity. Full power – it's all power consumed appliance. It consists of active power and reactive power, depending on the type of load. Active power is always in watts (W), the total – in the volt-ampere (VA). Devices – electricity consumers often have both active and reactive components of load. Resistive load This type of loading all consumed energy is converted into heat. On some units this is a major component. These devices include incandescent lamps, heaters, cookers, irons, etc. If they are specified power consumption of 1 kW, for their supply enough power stabilizer 1kVA. Reactive loads. All others. They, in turn, are subdivided into inductive and capacitive.
