Adjustable Motor Controller DC 660V 12V 24V 36V 48V 30A PWM DC Motor Speed Regulator Controller Start Stop Motor Controller Adjustable Motor Controller DC 660V 12V 24V 36V 48V 30A PWM DC Motor Speed Regulator Controller Start Stop Motor Controller Features: Speed controller ismade with high quality circuit board which ensures a longer service life. This simple and easy-to-use DC motor speed controller has an stable performance. Designed with a digital display that shows the rate in percentage of actual speed to maximum speed. This motor speed controller uses screw terminals for convenient and quick wiring. Comes with a momentary start/stop switch and a speed control 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 Speed Range: 0% to 100% RegulationMethod: Potentiometer Regulation Type: Regulating Current Control Frequency: 15KHz Wiring Type: Screw terminal Package Includes: 1 xSpeed 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. _x000D_ _x000D_
