Detailed Product Description

  BLDC  CONTROLLER

   MMT-DC4DPW25AL

The series provide efficient, smooth and quite controls for electric motorcycle, golf cart, go-cart, as well as industry motor speed or torque control. It uses high power MOSFET, PWM to achieve efficiency 99% in most cases. Powerful microprocessor brings in comprehensive and precise control to the controllers. It also allows users to set parameters, conduct tests, and obtain diagnostic information quickly and easily.

Feature

2)     Synchronous rectification, ultra low drop, fast PWM to achieve very high efficiency.

3)     Current limit and torque control.

4)     Battery current limiting available, doesnt affect taking off performance.

5)     Low EMC.

6)     LED fault code helps user debugging.

7)     Battery protection: current cut back, shutdown and warning at high or low battery.

8)     Thermal enhanced rugged aluminum housing. Rugged connectors.

9)     Thermal protection: current cut back on low temperature and high temperature to protect battery and controller.

10) Configurable 60-degree or 120-degree hall position sensor.

11) Support any number of poles.

12) Up to 60000 electric RPM. (Electric RPM = mechanical RPM * motor poles)

13) Three modes of regen: brake switch regen, release throttle regen, 0-5V signal regen.

14) High pedal protection: Disable operation if power up with non-zero throttle.

15) Current multiplication: Take less current from battery, output more current to motor!

16) ) Easy installation: 3-wire potentiometer will work.
