PWM DC 6V – 28V 3A Motor Speed Controller

This DC Motor Speed Controller allows the control of 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 of 3A to your DC motor or other DC load.

Specification:      

• Input supply voltage: 6V-28VDC
• The maximum output power: 80W
• The maximum continuous output current : 3A
• Duty Cycle adjustable: 5%-100%

Operating instruction:

1. Connect your DC motor (or DC load) to the motor terminals.
2. Connect a voltage of 6V-28V DC to the circuit making sure of the correct polarity of the connection. Note that the voltage applied to the motor will be supply voltage applied to the circuit. It is recommended to add an appropriately rated fuse inline with the positive supply in order to protect the circuit from any possible short circuits.
3. You can now control the speed of the motor through potentiometer.
