Frequently Asked Questions
Q: What types of motors is this DC motor speed controller compatible with?
A: This PWM speed controller is designed for DC (direct current) motors operating between 12V and 80V. It supports 12V motors up to 250W, 24V motors up to 350W, and 48V motors up to 500W. It is NOT compatible with AC (alternating current) motors — connecting to AC will damage the unit.
Q: How does the soft start feature work on this motor speed regulator?
A: The soft start function gradually ramps up motor speed from 0% to the set target speed over a user-defined period of 0 to 10 seconds (default: 1 second). This reduces sudden mechanical stress on the motor shaft and connected components, helping to extend the lifespan of your equipment. The slow stop feature works similarly, gently ramping speed down rather than cutting power abruptly.
Q: Can I set minimum and maximum speed limits on this controller?
A: Yes. Using the onboard programming buttons and digital display, you can set a minimum speed between 0% and 80%, and a maximum speed between 0% and 100%. You can also choose how much speed changes with each button press — options include 1%, 2%, 5%, 10%, 15%, 20%, or 25% per step.
Q: What is the PWM frequency of this speed controller?
A: This motor speed controller operates at a 21 kHz PWM (Pulse Width Modulation) frequency, which provides smooth, stable motor operation with minimal electrical noise across the full 0–100% speed range.
