How to make over under voltage protection relay
Hi friends in this video i have made an over under voltage protection circuit this circuit can be used for both ac and dc load you can set over voltage and under voltage limit when voltage goes above the over voltage limit or goes down the under voltage limit the relay turns off hope this video would be useful please like share and subscribe
