Frequently Asked Questions
Q: What type of motor is this PWM speed controller compatible with?
A: This speed controller is specifically designed for 220V AC-powered DC brushed motors only. It is not suitable for brushless motors, AC induction motors, or stepper motors. Always verify your motor type before connecting.
Q: What is the difference between peak load current and continuous current?
A: The peak load current (20A) is the maximum current the controller can handle for short bursts, such as during motor start-up. The continuous current (10A) is the sustained current it can safely carry during normal ongoing operation. For best performance and longevity, ensure your motor's running current does not exceed 10A continuously.
Q: How do I adjust the motor speed with this controller?
A: Speed is adjusted using the onboard potentiometer knob. Turning the knob varies the PWM duty cycle, which in turn changes the effective DC voltage delivered to the motor — ranging smoothly from approximately 10V to 210V under load. No external controller or software is needed.
Q: Is this controller suitable for installation inside an enclosure or control panel?
A: Yes. Its compact dimensions (85 × 57 × 37 mm) and fence-type screw terminal connections make it straightforward to mount inside a control box or panel. Ensure adequate ventilation around the unit, especially when operating near maximum continuous current.
