PWM Motor Speed Controller (DC 6V-28V 3A)

This DC Motor   Speed Controller allows the direction and speed of a DC motor using a   Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully  adjustable from 0%-100%. It is able to deliver 3A continuously to DC motor or other DC loads 

This DC Motor PWM Speed Controller/Regulator controls the speed of a DC motor using a Pulse Width Modulated (PWM) DC voltage from 6V to 28V with a Duty Cycle fully adjustable from 5%-100% using the onboard potentiometer. It can provide a continuous current of up to 3A to your DC motor or other DC load.Connect a voltage of 6V-28V DC to the circuit board making sure of the correct polarity of the connection. The voltage applied to the motor will be the supply voltage applied to the circuit board. We recommend adding an appropriately rated fuse inline with the positive supply in order to protect the circuit from any possible short circuits. NOTE: The ground connections to the power supply and the motor must be separate connections. Do not tie the "Power -" and "Motor -" connections together, otherwise the controller will not work.
