We will gradually phase out KD models, which are replaced by KDZ models.We use aviation plugs on KDZ models to against rain and dust damage.
Same price, but more reliable and more stable.
Please email us at sales@kellycontroller.com first if you really want to order KD model.
Please see KDZ48200.
KD Series Brushed DC Motor Speed Controller
Kelly KD programmable series 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 and harsh environment.
• 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.
• Support torque mode operation.
• Configuring current-voltage mode of field function on controller with field to achieve more reliable.
• Critical parameters can be configured with GUI to best fit your application.
• User program provided. Easy to use. No cost to customers.
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.
