  • This can NOT be used to the BRUSHLESS motor.
  • Do not reverse the positive and negative terminals of the DC power supply, otherwise the governor may be damaged.
  • The motor can be positive or negative, regardless of when the direction is inconsistent with expectations, can be changed by adjusting the direction of line sequence.
  • Adjustment potentiometer knob to change the governor output duty cycle, the motor speed change.
  • The use of 0-5V external voltage control line, the speed controller supports the use of an external DC voltage control.

How to use:

  1. First, remove potentiometer. (you may take it down from one side of the circuit board or potentiometer side down under your need);
  2. Second, connecting 0-5V DC control signal to the middle pin marking 0-5V;
  3. Thirdly, connecting the earth wire of 0-5V DC control signal to the connecting piece on the pin marking GND;
