It's a PWM speed controller which enables you to control the speed of those DC brush motors smoothly. It's ideal for applications like car motors, DC heater, bulb etc. providing nice adjustment of motor speed.
9-50V 2000W 40A DC Electronic Speeder PWM Motor Speed Controller 12/24/36/50V
Specific Power Control:
12V: 480W; 24V: 960W; 36V: 1440W；40V: 1600W; 50V: 2000W
PWM Working Principle:
BY changing the duty ratio of square wave(output) to adjust average current power from 0-100% on load, thus to change the motor speed or light brightness.
1.Universal DC brush motor speed control.
2.Control motor speed of cars(eg. car cooling fan motor, car fan motor, car windshield wiper motor, air condition fan motor)
3.Adjust speed of the conveyor of product lines, tube exhaust fan, treadmill, electric fan.
4.Adjust temperature of DC heater, brightness of common DC bulb.
