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

This DC motor speed controller allows the use of pulse width modulation (PWM) DC voltage to control the direction and speed of the DC motor, with a fully adjustable duty cycle within the range of 0% -100%. Can continuously provide 3A current to DC motors or other DC loads
The DC motor PWM speed controller/regulator uses pulse width modulation (PWM) DC voltage ranging from 6V to 28V to control the speed of the DC motor, and can fully adjust the duty cycle within the range of 5% -100% using an onboard potentiometer. It can provide up to 3A continuous current for your DC motor or other DC loads. Connect 6V-28V DC voltage to the circuit board, ensuring the correct polarity of the connection. The voltage applied to the motor will be the power supply voltage applied to the circuit board. We suggest adding a fuse of appropriate rating in series with the positive power supply to protect the circuit from any possible short-circuit effects. Attention: The grounding connection between the power supply and the motor must be a separate connection. Do not connect the "power supply -" and "motor -" together, otherwise the controller will not work.
