Are there any advantages of the product?
Technology is extremely high efficiency, torque, small heating, has been upgraded for many times and widely used in industrial production.

How to use it?
1. DC + (Power +): can be connected to a DC Power supply 12-40 v
2. DC - (Power): connect the negative DC Power supply
3. Motor +: connect the positive control Motor
4. Motor -: connect the negative control Motor
Adjust potentiometer knob can change speed output duty cycle, motor speed change wiring, the line must not touch heat sink. Potentiometer clockwise, the bigger the value.

What should I notice?
Do not exceed the rated voltage of the input voltage. Do not overload the output.
