DC Motor Speed Controller up to 20A, DC 12V ~ 48V w/ Reversible Switch

  • RM45.00

  • Product Code: Reversible Motor Speed Controller 20A
  • Availability: In Stock


DC Motor Speed Controller allows controlling both the speed and direction of a DC motor using a Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 0%-100%. The motor speed controller incorporates a high power MOSFET with a heat sink and can easily provide a continuous current of 20A to your DC motor or other DC load.



  • Adjustable speed with potentiometer
  • Forward and reverse switch
  • Wide range control uses PWM to vary the speed of DC motors.
  • Remote adjustment pot (included) connects to board by a 12" cable to header pins.
  • Terminal strip for power & Motor connections.
  • Power-On LED indicator



  • Working Voltage: DC 9V - 60V
  • Max. continuous current output: 20A
  • PWM pulse width modulation range: 0% -95%
  • Max. Frequency: 25KHz
  • Operating temperature: -20℃ - 40℃
  • Size: 90 x 50 x 35 mm

WARNING: This can NOT be used to the BRUSHLESS motor.
The controller is NOT reverse-polarity protected and will be damaged if connect the supply voltage with wrong polarity. Double check all connections before applying power and always turn off the power supply before making any wiring changes.

WARNING: Do not reverse postive and negative power loads, this will damage the controller.
