This product is a Pulse Width Modulation (PWM) speed controller designed to control the speed of DC⁤ brush motors. It’s an ideal choice for ​various applications including car motors and DC ⁣heaters and allows for smooth​ adjustment of motor⁤ speed.


This PWM ⁣controller boasts a wide voltage⁢ range⁣ of 10-50V, 40A, and can control motor speed⁢ up ‍to a maximum of 2000W. The product utilizes a PWM Modulation system ​to adjust‍ motor‍ speed from 5-100%. It is​ stable, highly efficient, and operates with minimal noise. ‌

The controller comes with a field-effect tube, drive IC, and 70μm⁣ copper sheet Printed Circuit Board (PCB) which significantly ‌enhance the efficiency ⁣of PWM​ wave output. A Potentiometer is provided for speed adjustment​ and the‍ product is encased in a⁣ protective​ case to ensure durability.

Specific Power Control

Power control varies according to ⁣voltage:
– 12V: 480W
– 24V: 960W
– 36V: 1440W
– 40V: 1600W
– 50V: 2000W

PWM Working Principle

The PWM controller operates by changing the duty ratio of​ the square wave(output). This adjusts the average current power from 0-100%⁢ on load, enabling changes in motor speed ‌or ‌light ⁣brightness.

Main Applications

– Universal DC brush motor speed control
– Control ​motor speed in cars, such as‍ car cooling fan motor, car fan motor,⁣ car windshield wiper motor, air condition fan motor
– Adjust the speed ​of product line conveyors, tube exhaust fans, treadmills, and electric fans
– Regulate ⁣the temperature of DC heaters‌ and the brightness of common DC bulbs


There ⁣are two types of this PWM speed controller:‌ (1) ⁢Potentiometer and (2) Potentiometer ⁣with an external wire for connection. ​
