• 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.
• Standard PC/Laptop computer to do programming. No special tools needed.
