Specification: 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 provides stable performance. Designed with a digital display that shows the percentage of actual speed to maximum speed. This engine speed controller uses screw terminals for convenient and quick wiring. Comes with a start/stop button and a potentiometer for speed control. Specifications: Input voltage range: DC6V-60V (input voltage should match the rated voltage of the motor) Output voltage : Linear with load Output current: 30 A Continuous current: 20 A Speed range: 0% to 100% Control method: potentiometer Control type: control current Control frequency: 15 kHz Wiring type: screw terminal Package includes: 1 x speed controller Note : 1. Please allow small size errors due to manual measurement. Thank you for your understanding. 2. The digital tube only shows 0-100 percent of full engine speed, not the actual engine speed. For example, if the maximum engine speed is 500 rpm, 500 rpm will display 100 and 250 rpm will display 50. Package List
