Note:
The input of the DC motor speed regulator is DC power.
Do not connect directly to AC power (for example: household 240V AC power), otherwise it will burn out! ! !
Do not connect the positive and negative terminals of the DC power supply in reverse , otherwise the speed regulator may be damaged.
The motor can be indifferent to positive and negative. When the running direction is inconsistent with the expected direction , the direction can be changed by adjusting the line sequence .
Adjusting the potentiometer knob can change the output duty cycle of the speed regulator and the motor speed.
