This DC Motor Speed Controller allows controlling the direction of a DC motor using a Pulse-- Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 0%-100%.
The motor speed controller can easily provide a continuous current of3A to your DC motor or other DC load.

Main technical parameters:
Input supply voltage:6V-28VDC
The maximum output power: 80W
The maximum continuous output current :3A
Duty Cycle adjustable:5%-100%
Size: 5cm*3.2cm (L*W)


Operating instruction:

Before you attempting to wire the controller, make sure power is off.
WARNING: DO NOT REVERSE POSTIVE AND NEGATIVE POWER LOADS.THIS WILL DAMAGE THE CONTROLLER.
TO CHANGE MOTOR DIRECTION, INTERCHANGE THE POSITIVE AND NEGATIVE WIRES OF MOTOR.
