Kelly has lunched KIM controller for AC Induction Motors, range from 24V to 72V, 100A to 500A. High voltage ac inducton motor controllers is coming soon.
Kelly KIM programmable 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.http://kellycontroller.com/ac-induction-motor-controller-kim24v-72v-c-85.html
(1)Intelligence with powerful microprocessor.
(2)Synchronous rectification, ultra low drop and fast PWM to achieve very high efficiency.
(4)Voltage monitoring on 3 motor phases, bus, and power supply.
(5)Voltage monitoring on voltage source 12V and 5V.
(6)Current sense on all 3 motor phases.
(7)Current control loop.
(8)Hardware over current protection.
(9)Hardware over voltage protection.
(10)Configurable limit for motor current and battery current.
(12)LED fault code.
(14)Rugged aluminum housing for maximum heat dissipation and harsh environment.
(15)Rugged high current terminals, and rugged aviation connectors for small signal.
(16)Thermal protection: current cut back, warning and shutdown on high temperature.
(17)Decelerating speed according to the brake rate when brake switch is active.
(18)Decelerating speed according to the brake rate at reverse. Configurable reversing accelerating function.
(19)Support three braking modes: release throttle braking, brake switch braking or reversing braking, analog signal variable braking. Configurable Decelerating Slip Frequency in configuration program.
(20)Support three-level speed: free (the controller will stop output), forward, and backward.
(21)Configurable high pedal protection: Disable operation if power up with high throttle.
(22)Current multiplication: Take less current from battery, output more current to motor.
