24v 36v 48v Bldc Motor Driver 30A

This bldc controller is applicable to BLDC motor, brushless dc motor, hub motor.
  • DC10/50DPW30BL

  • Keya

  • DC10/50DPW30BL

I: Features:

  • This controller has three manners of working: speed control, current control and open-loop control.

  • Control functions of braking, direction, enable, first-magnification, dual speed setting, etc. can be realized.

  • Maximum current limit can be adjusted.

  • 0-5V signal control way for external potentiometer, interior potentiometer and external analog quantity and soft start function.

  • Time setting function for soft start.

  • Overcurrent protection function

  • Overheating protection function

    When the temperature is too high, the speed controller will stop outputting and provide better safety for the moter and the speed controller.

  • High-speed control that full speed of one pole pair motor can reach 120000RPM

      Details refer to relevant contents.
