Frequently Asked Questions
Q: What type of motors is this DC motor speed controller compatible with?
A: This controller is designed specifically for DC brushed motors operating between 12V and 48V. It is not compatible with brushless DC motors, AC motors, or stepper motors. Always verify your motor's voltage and current ratings match the controller's specifications before installation.
Q: Can I use this controller for both forward and reverse motor operation?
A: Yes. This speed governor features built-in forward and reverse switching, allowing you to change the direction of your DC brushed motor with ease — no rewiring required. Simply use the directional switch on the module to toggle between forward and reverse.
Q: What is the maximum current this motor speed controller can handle?
A: The controller supports up to 70A continuous output current. While the product title references 200A, please refer to the verified specification sheet: the rated continuous output current is 70A. Ensure your motor and wiring are appropriately sized to handle the current load safely.
Q: How do I adjust the motor speed?
A: Speed is regulated via a potentiometer input (0–5V signal range), covering the full 0–100% speed range. The module includes a 10mm potentiometer mounting hole so you can integrate the control knob directly into your panel or enclosure for convenient, on-the-fly speed adjustment.
