Frequently Asked Questions
Q: What DC voltages is this PWM motor speed controller compatible with?
A: This PWM motor speed controller supports a wide input voltage range of DC 10V to 60V, making it fully compatible with 12V, 24V, 36V, and 48V DC motor systems — ideal for a broad range of applications from small hobby builds to larger power setups.
Q: Do I need a heatsink with this motor speed controller?
A: For light to moderate loads, the module can operate without additional cooling. However, when running at or close to the maximum 20A output current, attaching a heatsink or adding a cooling fan is strongly recommended to maintain safe operating temperatures and extend the module's lifespan.
Q: Can I use this controller for both forward and reverse motor control?
A: This module is designed for single-direction speed regulation (zero to full speed). It does not include a built-in forward/reverse switching function. For bidirectional control, an additional H-bridge or relay module would be required alongside this unit.
Q: How do I connect the potentiometer to control the speed?
A: The board features a standard 7mm potentiometer mounting hole. Simply fit a compatible rotary potentiometer into the hole and wire it to the designated terminals on the board's fence-type terminal block. Turning the knob smoothly adjusts motor speed across the full range.
