KEB72451X Electric Bicycle Brushless Controller 24V-72V 220A 4.5KW Regen

KEB72451X brushless motor controller 24V-72V, 220A, 4.5KW, with regeneration

Features:

• Specially designed controller for electric bicycles and scooters.
• Smart controller with powerful microprocessor
• Synchronous rectification, ultra-low drop, fast PWM for very high efficiency
• Electronic reversing
• Voltage monitoring on 3 motor phases, bus and power supply.
• Voltage monitoring on 12V and 5V voltage source.
• Current monitoring on all 3 motor phases.
• Current control loop.
• Hardware overcurrent protection.
• Hardware overvoltage protection.
• Support torque mode, speed mode, and balance mode.
• Configurable limit for motor current and battery current.
• Battery current limit available, does not affect acceleration performance.
• Increased starting current, more starting speed can be obtained.
• Low EMC.
• LED fault code.
• Protection battery: current reduction, warning and shutdown at configurable high and low battery voltage.
• Rugged aluminum housing for maximum heat dissipation in harsh environments.
• Rugged high-current terminals and rugged aviation connectors for signal wires.
• Thermal protection: current cut-off,high temperature warning and shutdown
• Adjustable 60 or 120 degree Hall position sensors
• Support motors with any number of poles
• Standard up to 40,000 electrical rpm. Optional high speed 70,000 ERPM and extra high speed 100,000 ERPM. (Electrical speed = mechanical speed * motor pole pairs).
• The brake switch is used to start regeneration.
• 0-5V brake signal is used to control the regeneration current.
• Support three modes of regenerative braking: regeneration when the brake sensor is turned on, regeneration when the throttle is released, smooth regeneration of the 0-5 analog signal variable AT.
• Tunable Accelerator Pedal Protection: The controller will not work if high throttle is detected when turned on.
• Current Multiply: Less current from the battery, more current to the motor.
• Easy installation: 3-wire potentiometer will work.
• Standard PC/laptop for programming. No special tools required.
• User program provided. Easy to use . Free for customers.

Main Features:

• Operating frequency: 16.6 kHz.
• Standby current batteries: <0.5 mA.
• 5 V sensor supply current: 40 mA.
• Supply current, PWR, 150 mA.
• Brake and throttle analog input: 0-5 volts. Creating a 0-5V signal using a 3-wire potentiometer.
• Full power operating temperature range: 0℃ to 50℃ ( controller case temperature).
• Operating temperature range: -30℃ to 90℃, shutdown 100℃ (controller case temperature).
• Maximum battery current: configurable
