Solenoid, Relay, Valve Driver with Current Regulation

https://www.electronics-lab.com/project/solenoid-relay-valve-driver-with-current-regulation/

The project presented here is a PWM current driver for solenoids, Relays, and valves. The board will regulate the current with a well-controlled waveform to activate and reduce power dissipation at the same time. The solenoid current is ramped up fast to ensure the opening of the valve or relay. After the initial ramping, the […]
