Kelly KD Brushed DC Motor Controller

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.

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.

• 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.

• 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.

• "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.
