Abstract

PURPOSE: To prevent a voltage stabilizing circuit from breaking down by cutting off an input on detecting an overvoltage applied across the voltage stabilizing circuit.
CONSTITUTION: To battery power supply 4, voltage stabilizing circuit 7 is connected via relay switch 6 (a load is connected to its output terminals 8 and 8'), and between storage battery 4 and circuit 7, protecting circuit 9 (consisting of Zener diodes ZD11 and ZD12, relay 12 and ZD protecting diode 13) for protecting circuit from a high voltage is connected in parallel. When storage battery 4 is disconnected from the charging circuit, circuit 9 is applied direct with a voltage between inputs 3 and 3', which flows a current through relay 12, and consequently switch 6 is held OFF to cut off voltage application to circuit 7, so that circuit 7 can be prevented from breaking down due to the high-voltage application.
