Abstract

The power source device has a rectifier for rectifying an output of the detector, a smoother, and a switching circuit for receiving the rectified output via the smoother. The output is alternately applied to two output terminals. A dummy burden is connected to one output terminal of the switching circuit , and a generating circuit connected to the second output terminal provides constnat voltage to the circuit breaker. A voltage monitoring circuit responsive to at least one of the output voltages of the generating circuit and the rectifier controls the position of the switching circuit. The dummy burden has a value, equal to a value of a totla burden of the generating circuit and the circuit breaker.
