1Pc 6-60V 12V 24V 36V 48V 30A PWM DC Motor Speed Controller If you are using this for motor speed control, please note - the maximum current indicated is inclusive of the inrush current produced when a motor is first started, under load, stalls etc. Please consider the excess current produced in these circumstances when considering your purchase as such conditions will damage the PWM. Wheel chair motors? Probably not. Scooter motors? Probably not. 24V XD3440 motor for a DIY bench grinder? Sure, should work great! 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 WM DC Motor Speed Controller Specifications: Input Voltage Range: DC6V-60V (input voltage should be same as motor rated voltage) Output Voltage: Linear with load Output Current: 0A-30A Continuous Current: 20A Speed Range: 0% to 100% Regulation Method: Potentiometer Regulation Type: Regulating Current Control Frequency: 15KHz Wiring Type: Screw terminal Note: This speed controller is rated maximum at 30A by the manufacturer. However, we rate it closer to 10A for continuous use and for higher voltages. Please bear this in mind when deciding if it is the correct controller for your devices.
