The input voltage should be equal to the rated voltage of the motor. It is not possible to input 220V household electricity.2. The input must distinguish between positive and negative polarity.3. The motor can be connected without distinguishing positive and negative, when the running direction is inconsistent with the expected, you can change the direction by adjusting the motor wire sequence.1The controller is equipped with a forward/reverse rotation switch. 2The controller is control the speed with a potentiometer with switch. 3Easy installation and convenient usages,simple operation,you can handle it easily. 4The controller can work in 9V,12V,24V,36V,48V,60V power supply. 5Professional and practical design with beautiful appearance.
