PWM Speed Controller (12V / 10A)

The PWM (Pulse Width Modulation) Speed Controller is an electronic module designed to control the speed of brushed DC motors by varying the duty cycle of the input voltage. It provides smooth and efficient speed regulation without significant power loss, making it ideal for applications requiring precise motor control. The module typically includes a rotary potentiometer for manual speed adjustment and built-in protection features for safe operation.
