KELLY ELECTRIC controller - works with 36V and 48V systems, just needs correct matching throttle. Kelly Part #: KBS48101L-L PLEASE BE AWARE THAT YOU MAY NEED TO ADAPT THE CONNECTORS TO YOUR THROTTLE, MOTOR AND BATTERY.
New model does NOT have RS-232 port. If buyer wants to program, a specialized cable and software are necessary - please contact Kelly as required.
Kelly KBS-L programmable BLDC motor controller provides efficient, smooth and quiet controls for electric motorcycles, golf carts, go-carts, as well as industry motors speed or torque control. Motor speed controller uses high power MOSFET, PWM to achieve efficiency 99% in most cases. Powerful microprocessor brings in comprehensive and precise control to BLDC motor controllers. This programmable brushless motor controller also allows users to set parameters, conduct tests, and obtain diagnostic information quickly and easily. Features: Intelligence with powerful microprocessor. Synchronous rectification, ultra low drop, fast PWM to achieve very high efficiency. Electronic reversing. Voltage monitoring on 3 motor phases, bus, and power supply. Voltage monitoring on voltage source 12V and 5V. Current sense on all 3 motor phases. Current control loop. Hardware over current protection. Hardware over voltage protection. Configurable limit for motor current and battery current. Support torque mode, speed mode, and balanced mode operation. Low EMC. LED fault code. Battery protection: current cutback, warning and shutdown at configurable high and low battery voltage. Rugged aluminum housing for maximum heat dissipation and harsh environment. Rugged high current terminals, and rugged aviation connectors for small signal. Thermal protection: current cut back, warning and shutdown on high temperature. Configurable 60 degree or 120 degree hall position sensors. Support motors with any number of poles. Configurable high pedal protection: the controller will not work if high throttle is detected at power on. Current multiplication: Take less current from battery, output more current to motor. Standard PC/Laptop computer to do programming. No special tools needed. General Specifications: Frequency of Operation: 16.6kHz. Standby Battery Current: < 0.5mA. 5V Sensor Supply Current: 40mA.
