Description
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.
Features
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
