6V-28V 3A 80W DC Brushed Motor Speed Controller PWM

This voltage controller module utilises pulse width modulation to regulate the voltage of your device, providing you with smooth and responsive performance. This voltage controller module utilises pulse width modulation to regulate the voltage of your device, providing you with smooth and responsive performance. Features: Size: 5 x 3.2 x 1.5 (cm) Input voltage: DC 6-28V Max current: 3A Potentiometer with switch function. Operating instruction: Before you attempting to wire the controller, make sure that the power is off. 1. Connect wires refer to the wiring diagram. 2. Turn on the power, and adjust the potentiometer. 3. The LED indicates the power up and the speed of motor. Warning: Do not reverse positive and negative power loads. This will damage the controller as there is no diode to protect it.
