システム。[Claims for Utility Model Registration] 1. A relay that turns on an alternating current voltage, a first rectifying and smoothing circuit that inputs the alternating voltage via this relay, and a predetermined direct current output from the first rectifying and smoothing circuit. a DC-DC converter that converts the AC voltage into a voltage; a second rectifying and smoothing circuit that receives the AC voltage and generates a voltage for driving the relay;
a first means for turning on and latching the drive of the relay by the second rectifying and smoothing circuit; an electromotive switch that generates a voltage when operated; and a first means for controlling the relay based on the voltage generated by the electromotive switch. and a second means for turning on the electromotive switch, which operates by being supplied with the DC voltage from the DC-DC converter, and has an interrupt control circuit, and may stop operating if the electromotive switch generates a voltage during operation. a load circuit that determines whether the operation can be stopped and outputs a signal indicating that the operation can be stopped; and third means for turning off the first means based on a signal. 2. The first means is a photothyristor,
The second means is a photodiode that makes the photothyristor conductive, and the third means is a photocoupler that discharges the gate voltage of the photothyristor and makes the photothyristor non-conductive. The power supply system according to item 1.
