12V-40V 10A DC PWM Motor Speed Controller 1M Cable It's a Potentiometer Knob Black400W DC PWM Motor Speed Controller allows you to regulate the speed of a DC motor with a Pulse Width Modulated (PWM) DC voltage and a Duty Cycle that may be adjusted from 10% to 100%. Your DC motor or other DC load can receive a continuous current of 0 10A at 12V 40V DC from the motor speed controller. Your DC motor or other DC load can receive an 8A continuous current from the motor speed controller. The circuit also incorporates a 10A fuse, as well
