The converter is intended to supply automatic vacuum circuit breakers and other loads with a capacitance of up to 4700 µF.
When a capacitor bank of more than 4700 µF is used, a 25 W, 47 Ω wire-wound resistor must be connected in series with the bank to limit the charging current.
The converter can be used inside a vacuum circuit breaker or other electronic equipment.
The converter is built to climatic version У, siting category 3.1 (ГОСТ 15150-69), for operation at −25 to +55 °C, relative humidity up to 80 % and atmospheric pressure of 650 to 800 mmHg.
The converter is intended for use in a non-explosive atmosphere free of gases and vapours in concentrations that attack metal or insulation, and free of saturated water vapour and conductive dust.
