Motor Speed Controller DC 4.5–35V PWM 5A 90W
Product Description
The DC Motor Speed Controller (4.5–35V, 5A) is a compact and efficient PWM controller designed to precisely regulate the speed of brushed DC motors. Using Pulse Width Modulation (PWM) technology, it provides smooth speed control with minimal power loss and high efficiency.
This controller is ideal for DIY electronics projects, robotics, automation, fans, pumps, and small DC motor applications.
The onboard potentiometer allows easy manual speed adjustment, while the wide voltage range makes it compatible with many DC power sources.
