50A 5-40VDC - MOSFET PWM Driver Module - HW-532 - Optoisolation

PWM driver module - HW-532 equipped with 1 MOSFET transistor. Dedicated to control devices using a PWM signal (DC motors, valves, heaters, etc.).
Widely used for the control and smooth regulation of the rotation of motors, solenoid valves and other devices. The optocoupler ensures the safety of the controller by preventing the operating voltage from entering the control circuit. This galvanic isolation is realized by SHARP PC817 optocoupler. The optocoupler also prevents interference from reaching the controller, which will significantly improve system stability.
