Start/Stop Switch and Speed Control: Includes a momentary start/stop switch and a speed control potentiometer for easy and precise speed adjustments. Specification: 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. Package List
