KIM AC Induction Motor Speed Controller

Kelly's programmable AC induction motor controllers provide 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.

Features:
• Intelligence with powerful microprocessor.
• Synchronous rectification, ultra low drop and fast PWM to achieve very high efficiency.
• Electronic reversing.
• Voltage monitoring on 3 motor phases, bus, and power supply.
• Voltage monitoring on voltage source 12V and 5V.
• Current sense on all 3 motor phases.
• Current control loop.
• Hardware over current protection.
• Hardware over voltage protection.
• Configurable limit for motor current and battery current.
• Low EMC.
• LED fault code.
• Battery protection: current cutback, warning and shutdown at configurable high and low battery voltage.
• Rugged aluminum housing for maximum heat dissipation and harsh environment.
• Rugged high current terminals, and rugged aviation connectors for small signal.
• Thermal protection: current cut back, warning and shutdown on high temperature.
• Decelerating speed according to the brake rate when brake switch is active.
• Decelerating speed according to the brake rate at reverse. Configurable reversing accelerating function.
• Support three braking modes: release throttle braking, brake switch braking or reversing braking, analog signal variable braking. Configurable Decelerating Slip Frequency in configuration program.
• Support three-level speed: free (the controller will stop output), forward, and backward.
• Configurable high pedal protection: the controller will not work if high throttle is detected at power on.
• Current multiplication: Take less current from battery, output more current to motor.
• Easy installation: 3 wire potentiometer can work.
• Remove fault code LED driver.
• Current meter output.
• Standard PC/Laptop computer to do programming. No special tools needed.
• User program provided. Easy to use. No cost to customers.
