8 best transformer voltage regulators

The device is intended for leveling voltage deviations in the electrical network. Reduces the negative effects of pulsed overvoltage, surges, noise. The principle of operation of a single-phase voltage transformer is based on a change in induction as the conductor moves along a coil with a winding. The main advantage of the stabilizer is to provide high accuracy of output parameters, the ability to withstand peak overloads. Specifications for selection: input voltage range, power, degree of accuracy in percent, mass-dimensional properties.
