PWM DC motor speed controller 12-40V 400W + potentiometer + fuse
0
Description
PWM DC motor speed controller 12-40V 400W + potentiometer + fuse
The PWM controller module enables precise speed control of DC motors, driving proportional valve coils and other loads using a pulse-width modulated signal. The device operates over a wide voltage range from 12V to 40V DC, supporting a maximum load current of up to 10A. This provides a maximum output power of 400W.
The duty cycle adjustment range is from 10% to 100%. Parameter changes are made using the built-in potentiometer. An additional connector on the PCB allows an external potentiometer to be connected. The module is factory fitted with a 10A fuse that protects the circuit from overload.
Example applications
- Smooth speed control of brushed DC motors
- Brightness control for lighting and LED modules
- Performance control of DC fans
- Control of proportional valve coils
- Power control for DC-powered heaters
Important operating information
The controller must not be used to drive brushless motors. The driver does not have reverse-polarity protection on the supply voltage-connecting power with incorrect polarity will permanently damage the module.
