Specifications: The motor speed controller has an input voltage range of 9V to 60V and can deliver an output current ranging from 0A to 20A. It is rated for continuous power output of up to 1200W Application: The dc motor driver is suitable for brush motor speed regulation, and dimming regulation of lights in DC circuits. Note: The motor cannot be used in electric vehicles Speed Controller: Our motor control board allows for speed regulation via a potentiometer and also supports adjustment for clockwise and counterclockwise rotation Instruction: The Thick red wire for the positive terminal of the power supply, thick black wire for the negative terminal; thick blue wire for the positive terminal of the motor, and thick green wire for the negative terminal of the motor PWM: The advantage of using Pulse Width Modulation (PWM) for dimming or speed control is that it enables the full utilization of the power supply's , resulting in highly efficient circuit performance
