The principle of operation of the stabilizer based on the regulation of the output voltage by pulse width modulation. At the input and at the output of the device has analog filters, effectively smoothing the impulse noise in the network. In the stabilizer used transit scheme "zero wire" - from input to output device that enables connection of the user equipment, the efficiency of which depends on the correct phasing of the input voltage.

The stabilizer has two modes of operation:

- VIP mode in which stabilization is no fixed voltages with an accuracy of ±1.5% range of adjustment output voltage (200-240V);

- economy mode, in which stabilization is outside the specified range of output voltages. The output voltage within the limits, established by the user equals the input voltage with almost no loss of energy, which can significantly save energy. The minimum acceptable limit of the range of 200V, maximum - 240V, which does not extend beyond the passport data of most household appliances. In case of short circuit (SC) triggers the built-in short circuit protection.
