Kathlen PWM DC Motor Speed Controller - DC 6-60V/30A- LED Display Stepless DC Motor Speed Controller with Adjustable Potentiometer

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 Rapidity Range: 0% to 100% Regulation Method: Potentiometer Regulation Type: Regulating Current Control Frequency: 15KHz Wiring Type: Screw terminal Package Includes: 1 x Rapidity 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 rapidity percentage, not the actual motor rapidity. For example, if the maximum motor rapidity is 500 rpm, it will display 100 at 500 rpm and 50 at 250 rpm.
