Size: length 30MMx width 26MM (without handle) x height 14MM 8. Weight: 0.013KG Precautions: The input of the DC motor governor is DC power, and it cannot be directly connected to AC power (for example: household 220V AC power), otherwise it will burn out! ! ! Do not connect the positive and negative terminals of the DC power supply in reverse, otherwise the governor may be damaged. The motor can be divided into positive and negative. When the running direction is not consistent with the expectation, the direction can be changed by adjusting the line sequence. Adjusting the potentiometer knob can change the output duty ratio of the governor, and the motor speed changes.
