specification

Attention:
* The input of the DC motor speed controller is direct current. Do not connect to alternating current directly, 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.
* This type of speed governor is used for brushed DC motors, and is not suitable for speed control of brushless DC motors; nor can
it be used as a voltage regulator or regulator.
* The motor can be positive or negative. When the running direction is inconsistent with the expectation, the direction can be
changed by adjusting the line sequence.
* Adjusting the potentiometer knob can change the duty cycle of the governor output and the motor speed.
