How to correctly select a voltage regulator? What is needed voltage – single phase or three phase? Do I need to put some voltage to different consumers, or better put one at all? What power is required voltage? The answer to these and many other questions can be found in our article! The main characteristic is a voltage stabilizer of the connected load. It is based on This option will select a particular model. Please keep in mind that the power of the stabilizer should be equal to or slightly more power to the instrument for the protection of which it is intended. Thus, calculating the capacity of all devices that need protection to ensure that we can easily determine which model is the voltage regulator is needed in this case. You can, of course, without going into lengthy calculations, purchase stabilizer maximum power. However, such a model would be costly, and whether it makes sense to install this stabilizer, whose power will be used only by 15-20%.

It is very important to remember that some appliances are starting currents, several times higher than the nominal currents. It is typical for devices with asynchronous motors in the circuit, such as refrigerators, pumps, and therefore the stabilizer for such devices must choose from two – three-time power reserve. How to protect a large number of appliances simultaneously, such as in your office? Must take into account several factors: first, as organized layout voltage in the building, ie how it will be convenient to embed a common single-phase or three phase voltage or more separate stabilizers to the already existing Electricity and secondly, as a rule, one big regulator, equal in power to several individuals, is cheaper.
