Under Voltage Lockout Relay – Latching Voltage Monitor

https://www.electronics-lab.com/project/under-voltage-lockout-relay-latching-voltage-monitor/

This project prevents/disconnects the load when an under-voltage condition occurs. The circuit latches the output when input sense voltage drops below the lockout threshold. Lockout threshold voltage can be adjusted using the onboard trimmer potentiometer PR1.  Tactile switch SW1 is provided to reset the latch when input sense voltage is back to normal. The circuit […]
