Kelly KIM series controller is designed for AC induction motors. It provide high efficient, smooth and quite controls for small and midsize electric vehicles, such as golf carts, go-carts, stacking cars, forklifts, hybrid vehicles, electric boats, as well as industry motor speed or torque control. It uses high power MOSFET, PWM to achieve efficiency 99% in most cases. Powerful microprocessor brings in comprehensive and precise control to the controllers. It also allows users to set parameters, conduct tests, and obtain diagnostic information quickly and easily.
Kelly KIM AC induction motor controllers range from 24V to 72V, 100A to 500A.<BR>
