7KW-8KW Kelly Programmable Motor Controller(KEB72101) with Braking Regenerative Function

Kelly Progammable Controller(BEST CONTROLLER IN CHINA) KEB72101 can drive high power HUB MOTOR 7000W or 8000W/72V,and with Braking Energy Recovery function. Can be configurated the DATAS on the computer connected   Details specification as follows, Features: • Specially designed for electric bicycle and scooter. • 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. • Support torque mode, speed mode, and balanced mode operation. • Configurable limit for motor current and battery current. • Battery current limiting available, doesn’t affect taking off performance. • More startup current ,can get more startup speed. • 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. • Up to 40,000 electric RPM standard. Optional high speed 70,000 ERPM, and ultra high speed 100,000 ERPM. (Electric RPM = mechanical RPM * motor pole pairs). • Brake switch is used to start regen. • 0-5V brake signal is used to command regen current. • Support three modes of regenerative braking: brake switch regen, release throttle regen,0-5V analog signal variable regen. • 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. • Easy installation: 3-wire potentiometer will work. • Current meter output. • Standard PC/Laptop computer to do programming. No special tools needed. • User program provided. Easy to use. No cost to customers.
