PWM DC Motor Speed Regulator 35V/5A – Mini DC Speed Controller

The PWM DC Motor Speed Regulator (3V–35V, 5A) is a compact controller designed for smooth and efficient DC motor speed control. It uses Pulse Width Modulation (PWM) to vary motor speed from 1% to 100% while maintaining torque. Suitable for DIY, robotics, and automation projects, this controller supports a wide voltage range and features a simple knob for easy adjustment.

The PWM DC Motor Speed Regulator (3V–35V, 5A) is a compact and efficient solution for precise speed control of DC motors. Using Pulse Width Modulation (PWM) technology, this mini controller allows smooth and adjustable motor speed control without sacrificing torque.

Designed for DIY projects, robotics, automation, and small industrial applications, the regulator supports a wide DC voltage range and delivers stable performance with low power loss. A built-in potentiometer knob lets you easily adjust the motor speed from 1% to 100% duty cycle.

⚠️ Important: This controller supports DC input only. Connecting AC power (such as 220V AC) will permanently damage the module.
