Automatic reset over-voltage protection circuit diagram

Published:2011/8/3 2:40:00 Author:Rebekka | Keyword: Automatic reset, Over-voltage protection | From:SeekIC

The circuit includes 3 circuit parts:power supply, trigger start and control. The power supply switch of the load R1 is controlled by bidirectional thyristor ZN6346. When the AC voltage is over high, the A point voltage of steady flow component 1N5314 will rise and the unidirectional thyristor will be conducted and the transistor will be closed. The main bidirectional thyristor will be closed at the same time, the load will be protected from damaging.
