FIELD: electricity.
SUBSTANCE: in a device an optical coupler is made as a transistor one, a light radiator of which is connected serially into a circuit of a voltage sensor, connected in parallel with the main source of supply, and a phototransistor of the optical coupler is connected between the transistor base and the common output of the supply sources. Besides, the other output of the reserve supply source is connected via a collector-emitter transition of the transistor with the other output of the load.
EFFECT: reduced consumption from the main source of supply, simplified device and its increased reliability.
