KD PM Brushed DC Motor Speed Controller

Kelly KD programmable PM brushed DC motor controller provides efficient, smooth and quite controls for electrical vehicles like golf cart, electric motorcycle, fork lift, as well as electric boat and industry motor speed control. Motor speed controller uses high power MOSFET, fast PWM to achieve efficiency 99% in most cases. Powerful microprocessor brings in comprehensive and precise control to brushed motor controllers. This programmable motor brushed controller also allows users to set parameters, conduct tests, and obtain diagnostic information quickly and easily.

Features:
•Intelligence with powerful microprocessor.
• Synchronous rectification, fast PWM, and ultra low drop to provide high efficiency.
• Rugged aluminum housing for maximum heat dissipation.
•Current loop and over current protection for both field coil and armature.
•Current multiplication. Usually the armature current is much higher than the current drawn from battery.
•LED blinking code indicates fault sources.
•Battery protection: current cutback and turnoff when battery voltage is too low.
•Thermal protection: current cuts back at high temperature and low temperature to protect battery and controller.
• Critical parameters can be configured with GUI to best fit your application.

Additional Features (Terminals available on back side):
Following features are configurable through series communication with a host PC.
•"MAIN RLY" can be configured as a Peak and Hold Main Contactor coil driver.
•"BEEP/MTR" can be configured to drive reverse alarm or current meter. Can drive Kelly Ampmeter directly.
• BRK-SW as Brake Switch is required for regeneration.
• BRK-AN as Brake analog input can be configured for continuous variable regeneration.
• TPS2-AN can be configured as alternative throttle input. 3-wire pot or 0-5V sensor can work with the input. Please configure as 0-5V throttle should the pin be used.
• Optional Waterproof.
