Abstract

PURPOSE:To prevent a load device against system failure, by controlling the stoppage of current supply by the command on a load device side with stable power supplied even in service interruption. CONSTITUTION:The terminal voltage of a battery 3 floatingly charged by a rectifier 1 is detected with a low voltage detection circuit 2. When the power gets closer to the final discharge voltage, a signal is sent to a load device 4 through a photocoupler 6. The load device 4 receives this signal, ascertains the on-line state, etc., and trips a connecting device 7 by conducting the photocoupler 5 when the processing is completed.
