  • Regulate Range - Input voltage: DC 10-55V, Continuous current: 60A, Max current: 100A. Current modulation, NOT Pulse Width Modulation (PWM)
  • Easy to install and operate - Simple potentiometer knob adjusts the motor speed from 0% ~ 100% smoothly
  • Conveniently change the motor direction - The Forward-Brake-Reverse switch is convenient to change the direction of the motor without adjusting the order of the motor lines
  • Excellent heat dissipation performance - Aluminum shell prevents it from easily damaged, holes on its side and top and six heatsinks are helpful for heat dissipation
  • Accurate display - The LED display is accurate to show 0 ~ 100% of the motor speed.

UCTRONICS DC 10-55V/100A Motor Speed Control is designed to control the direction and speed of a DC motor by modulating current from 0 ~ 100A with working voltage DC 10-55V. This DC motor speed controller can be widely used in controlling the speed of a fan/pump/other DC load, or to dim the brightness of DC lamps or LEDs.

1. Cannot connect to AC power directly, it is a DC motor controller.

2. Cannot reverse the positive and negative polarity of the POWER.

3. Cannot reverse the positive and negative polarity of the MOTOR.

4. Cannot control a brushless motor, this controller only supports brush motor.

5. Double check all connections before applying power and always turn off the power supply before making any wiring changes.

6. Speed Control Type: Current modulation, NOT Pulse Width Modulation (PWM)
