Frequently Asked Questions
Q: What voltage range does this PWM DC motor speed controller support?
A: This controller supports a DC input voltage of 10V to 60V, with a recommended operating range of 12V to 48V for optimal performance and longevity.
Q: Does this motor speed regulator have overcurrent protection?
A: Yes. The controller features built-in overcurrent and overload protection with an adjustable current limiting range of 1A to 10A, helping safeguard both the controller and your connected motor.
Q: What size motors is this PWM controller compatible with?
A: It is compatible with 12V DC motors rated under 120W and 24V DC motors rated under 200W. Always ensure your motor's rated wattage falls within the supported range for your supply voltage.
Q: How does the PWM speed adjustment work?
A: The onboard B100K potentiometer allows you to smoothly adjust the PWM duty cycle from 0% to 100%, which in turn varies the effective voltage delivered to the motor — giving you full stepless speed control from a complete stop to maximum speed.
Q: What is the PWM frequency of this motor speed controller?
A: The controller operates at a PWM frequency of 21kHz, which is above the audible range for most listeners, resulting in quieter and more efficient motor operation compared to lower-frequency controllers.
