Kelly KVD programmable motor controllers provide efficient, smooth and quiet controls for electric motorcycle motor control. It uses high power MOSFET’s and, PWM to achieve efficiencies of up to 99% in most cases. A powerful microprocessor brings in comprehensive and precise control to the controllers. It also allows users to adjust parameters, conduct tests, and obtain diagnostic information quickly and easily. Customers can program the KVD controller on PC software and/or via Android App. Customers may add USB cable for programming Via PC or Bluetooth module if they want to use Android Tablet. (not tuning generally required from E&C controllers for baseline operation)
E&C KVD features an improved HEATSINK Design & enclosure over standard KVD , KBL/KLS controllers which results in improved waterproofing and peak currents.
Motor Current Limit, 30 seconds: 200A
Motor Current Limit, continuous: 75A

FYI: Kelly Controllers have changed the naming Scheme of the KVD lineup. It is possible older controllers will be labeled as a 7215No or 7212NX, this product is a direct replacement of those. Do not be alarmed, the firmware, tune, internals & hardware have not changed as we are told by Kelly Controller.
