Features High Quality: The DC speed controller ensures extended service life for this DC motor speed controller. Input voltage 60V, continuous current is 20A, control frequency of 15KHz, fence type wiring. The speed controller is made of high quality circuit board to ensure a long service life. Stable Performance: The speed controller easy and practical to use. Has stable performance. With momentary start/stop switch and speed control potentiometer, you can check the forward or backward direction when using it and use the switch to stop the DC motor. Digital Display: Motor speed controller with digital display shows actual speed as a percentage of maximum speed, keeping you in control at all times. Quick Respond: Includes a momentary start/stop switch and a speed control potentiometer for complete control over your DC motor. Convenient: Screw terminals make wiring simple and convenient. The motor speed controller uses screw terminals for easy and quick wiring and is designed with a digital display that shows the actual speed percentage at maximum speed. Specifications:  Input Voltage Range: DC6V-60V (input voltage should be same as motor rated voltage) Output Voltage: Linear with load Output Current: 30A Continuous Current: 20A Speed Range: 0% to 100% Regulation Method: Potentiometer Regulation Type: Regulating Current Control Frequency: 15KHz Wiring Type: Screw terminal Package Includes: 1 x Speed Controller Note: 1. Please allow small size error due to manual measurement. Thanks for your understanding. 2. The digital tube only displays 0-100 motor full speed percentage, not the actual motor speed. For example, if the maximum motor speed is 500 rpm, it will display 100 at 500 rpm and 50 at 250 rpm.
