Features: The speed controller is made of high-quality circuit board, which ensures a longer service life. This simple and easy-to-use DC motor speed controller has stable operation. The output current of this motor speed controller can be adjusted from 0A to 30A, and it is simple to set. Designed with a digital display that shows the percentage of actual speed to the maximum speed. This motor speed controller uses screw terminals for convenient and quick wiring. The positive and negative controllers must be properly connected, otherwise the object may be burned. The input voltage of the driver is better to be the same as the rated voltage of the motor.
