PWM DC Motor Speed Controller AC/DC 80-230V, 0-220V Output

PWM Motor Speed Controller — AC/DC 80–230V Input | 0–220V Adjustable Output

Take full control of your DC permanent magnet motor with this compact, high-performance PWM Motor Speed Controller Board. Designed for a wide range of industrial and workshop applications, this controller module delivers smooth, linear speed adjustment from a complete stop (0V) all the way up to full speed (220V) — all within a rugged metal shell that's easy to mount and install.

Made in China.

Key Features

• Universal Input Compatibility: Accepts both AC and DC power supply in the range of 80–230V, making it highly versatile for different workshop and industrial setups.
• High-Power MOS Tube PWM Drive: Uses pulse-width modulation (PWM) technology — not thyristor — for stable, precise, and near-silent speed regulation.
• Smooth Linear Speed Control: Speed adjusts gradually and uniformly from 0V (stopped) to 220V (full speed) with no sudden jumps or surges.
• Soft-Start Function: Eliminates start-up shocks and vibrations; the motor accelerates gently on power-up and decelerates smoothly on power-off.
• Emergency Pause & Start: Dedicated port-position function for instant pause and restart — ideal for time-sensitive operations.
• Adjustable Output Voltage Range: Output voltage is tunable to match your motor's requirements, allowing you to increase or decrease the operating range as needed.
• Compact Metal Shell: Dimensions of 110mm × 78mm × 35mm make it easy to integrate into existing equipment enclosures.
• Ultra-Low Noise Operation: Engineered for stable performance with minimal electromagnetic noise during motor control.

Frequently Asked Questions

Q: What type of motors is this PWM motor speed controller compatible with?

A: This controller is designed specifically for DC permanent magnet 2-wire motors rated between 48V and 220V, with motor power ratings from 30W up to 550W. It is not suitable for AC motors or brushless DC motors.

Q: Can I use this motor controller with both AC and DC power supplies?

A: Yes. The controller accepts both AC and DC input in the 80–230V range, giving you the flexibility to use it with a wide variety of power sources in workshop or industrial environments.

Q: How does the soft-start function work on this PWM controller board?

A: The soft-start function gradually ramps up the motor speed upon power-on, preventing sudden mechanical shock or vibration. Similarly, when powered off, the motor decelerates smoothly rather than stopping abruptly, extending the life of your motor and connected equipment.

Q: Is this motor governor easy to install in existing equipment?

A: Yes. The compact metal-shell design (110mm × 78mm × 35mm) makes it straightforward to mount within most equipment enclosures. Its simple 2-wire DC motor output connection keeps wiring minimal and manageable.
