Product Description

Precisely control the speed of brushed DC motors at 12 V / 24 V / 36 V / 48 V with this high-power 2000 W PWM controller. The well-ventilated metal case protects the electronics and helps dissipate heat, while the digital display shows the speed percentage (0–100%) for accurate adjustments. The potentiometer includes an integrated mechanical On/Off/On switch, enabling not only start/stop but also reversing the rotation direction (FWD–OFF–REV) of the motor. Designed for applications requiring high torque and quick response (cutters, industrial fans, DC pumps, DIY projects), the controller operates at a 15 kHz frequency for smooth running and reduced motor noise. Screw terminals simplify wiring, and quality electronics ensure long-term reliability.

Note: compatible only with brushed DC motors. To protect the motor and the controller, set the potentiometer to 0% before changing direction and use properly rated cables/terminations. The maximum available power depends on the supply voltage, motor current, and cooling conditions.

Pinout:

From left to right, the pins are as follows:

 - Motor− (M−)

 - Motor+ (M+)

 - Power − (GND)

 - Power + (VIN)

 - Digital display

Usage recommendations:

• Observe the polarities VIN+/GND and M+/M−.
• Select cables and fuses sized for the current (e.g., up to 40 A continuous).
• For heavy loads, install the controller in a well-ventilated area; add extra cooling if necessary.
• Do not use with brushless (BLDC) or AC motors.
