12V–48V 40A 2000W DC Motor Speed Controller with External Pot

12V 24V 48V 40A DC Motor Speed Regulator PWM Controller 2000W is a PWM speed controller which enables you to control the speed of those DC brush motors smoothly. It's great for applications like car motors, DC heater, bulb etc. providing nice adjustment of motor speed. Its best speed controller for higher current rating and wide voltage range with best reliability.

Voltage range can be utilize in engineering system and e-bike motors to speed control.

Features:

• Wide voltage range, 10-50V, 40A, max. 2000W for motor speed control & HOO.
• Apply PWM Modulation system to adjust motor speed from 5-100% .
• Stable in working, high efficiency and low noise.
• Field-effect tube, drive IC, 70μm copper sheet PCB for higher efficiency of PWM wave output.
• Potentiometer for speed adjustment, protective case creates better durability.

PWM Working Principle:

By changing the duty ratio of square wave(output) to adjust average current power from 0-100% on load, thus to change the motor speed or light brightness.

Specifications:

Main Applications:

• Universal DC brush motor speed control.
• Control motor speed of cars (e.g. car cooling fan motor, car fan motor, car windshield wiper motor, air condition fan motor)
• Adjust speed of the conveyor of product lines, tube exhaust fan, treadmill, electric fan.
• Adjust temperature of DC heater, brightness of common DC bulb.
