This is a DC 9-55V 40A 2000W PWM Motor Speed Controller With Potentiometer. This DC Motor Speed Controller allows controlling speed of a DC motor using a Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 10%-100%.
Features:
- Maximum Power: 2000W
- The speed of the DC motor can be controlled by adjusting the pulse width modulation (PWM).
- The knob realizes 0-100% adjustment, supports step-less speed regulation, and facilitates positioning speed.
- Operating voltage range: 9 55 VDC
