Kelly KSL Brushless and Sensorless Motor Controller

Product Description

General functions:
*Extended fault detection and protection. LED flashing code indicates fault sources.
*Monitoring battery voltage. It will stop driving if battery voltage is too high. It will cut back then stop driving if voltage is going too low.
*Built-in current loop and over current protection.
*Controller temperature measurement and protection
*Configurable and programmable with RS-232. Software upgradeable.
*Provide 5V sensor supply
*Reverse switch. Closing to ground is to activate.
*0-5V: Default to throttle input.
*Optional CAN bus. ( NA*)
*Optional supply voltage 8V-30V.

Features:
*Intelligence with powerful microprocessor.
*Synchronous rectification, ultra low drop and fast PWM to achieve very high efficiency.
*Current limit.
*Battery current limiting available. Doesn't affect taking off performance.
*Low EMC.
*LED fault code helps user debugging.
*Battery protection: Current cut back, shutdown and warning at high or low battery.
*Rugged aluminum housing for maximum heat dissipation. Rugged connectors.
*Thermal protection: Current cuts back on low temperature and high temperature to protect battery and controller.
*Current multiplication: Take less current from battery, output more current to motor!
*Easy installation: 3-wire potentiometer will work.
*Stuck Rotor protection.
