Connection:

1.Pls do not connect AC power directly(Such as:110V AC),the input volt of this controller should be DC, otherwise it will be burned out
2.Positive and negative pole of the POWER can not be reversed
3.Positive and negative pole of the MOTOR can be reversed. When the direction of operation is inconsistent with your expectations, you can change the direction by adjusting the order of the line
4.Adjust the potentiometer knob to change output duty cycle, thereby changing the motor speed

Note:

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.
