Precautions and instructions for use (Be sure to pay attention to the opposite when inputting voltage)
1. The DC motor governor can input DC power, and can not be directly connected to AC power (such as: 220V AC) or it will burn out.
2. The positive and negative poles of the DC power supply cannot be reversed, otherwise the governor will be damaged.
3. The motor can be divided into positive and negative poles. When the running direction is inconsistent with the expectation, the direction can be changed by the adjusting sequence of the line.
4. The potentiometer knob can change the governor output duty cycle to change the motor speed.
