The input voltage should be equal to the rated voltage of the motor. You cannot input 220V household power.2. The input must distinguish between positive and negative polarity.3. The motor can be connected without negative. When the running direction is inconsistent with the expected direction, the direction can be changed by adjusting the motor wire sequence.Package List1100% and high quality. 2Made of high quality material, durable and long service life 3Adopt the speed control mode of potentiometer, it has stable performance. 4The adjustable speed range is from 0%-100% 5Widely used in industrial DC motor speed regulation, industrial conveyor belt speed regulation, lighting and lighting mediation, computer power supply cooling, DC fan, etc.
