power supply cavity monitoring circuit

Published:2011/6/4 11:29:00 Author:John | Keyword: power supply, cavity | From:SeekIC

Low level electricity logic circuit partially goes through the optical coupling, so that the power supply is isolated. When the power supply fails, the output level electricity is down to the logic level. Adjust the output of trigger to turn off the circuit. The response time of the circuit is 2m8. When AC voltage is normally over zero, there is no effect on the circuit. Power consumption of the circuit is 50mW.
