12V 24V Max 20A PWM DC Motor Stepless Variable Speed Control Controller Switch Product Description 100% Brand New This can not be used for brushless motor Parameters: motor speed controller input voltage range is 9-60V, output current range is 0-20A, continuous power is 1200W. Application: the dc motor driver can be used to brush motor speed regulation, light dimming regulation in the DC circuit.Note: The motor cannot be used in electric vehicles. Speed Control: our motor control board can regulate motor speed by potentiometer;what's more, it support clockwise/anticlock-wise rotation adjustment. Features and Specification Easy Wiring: thick red wire for the positive of the power supply, and thick balck for the negative; thick blue wire for the motor positive, and the thick green for the motor negative. PWM: the advantage of using a pulse width modulation (PWM) method for dimming /speed regulation is that the energy of the power supply can be fully utilized and the circuit is highly efficient.
