Than the stabilizers of the voltage calm are good

Often consumers are wondering what the accuracy of stabilization of the input voltage is necessary for the power supply of one or another technique? This issue is especially important when you have to decide on the protection of one or another expensive household appliances using a voltage stabilizer. Are all voltage stabilizers equally useful? When choosing the accuracy of stabilization, one should be guided by the parameters of a particular electrical appliance, which are indicated in its passport. In the absence of the latter, the necessary information can be found in the manufacturer’s service center. Basically, the requirements for the accuracy of the boundaries of the supply voltage are determined by GOST 13109-97, which indicates the maximum permissible voltage deviations in the network no more than 10%. That is, if you take a rated voltage of 220 V, then the valuable values ​​of the supply voltage will be maximum values ​​from 198 to 242 V. It can be said that most voltage stabilizers have obviously the best characteristics of voltage regulation, which usually do not exceed 5% of the face value. Therefore, the issue of determining the appropriate voltage stabilizer to power specific devices can be reformed as the issue of finding the optimal. Consider this issue from the point of view of the stepping principle of regulation, which use modern stabilizers of the voltage of the calm, and also figure out how this principle of regulation of the operation of certain electrical appliances affects.
