KDHB High Power Series/PM Motor Speed Controller
Kelly KDHB programmable high power series/PM brushed DC motor
controllers provide efficient, smooth and quite controls for electrical
vehicles like golf cart, go-cart, electric motorcycle, fork lift, hybrid
vehicle, as well as electric boat and industry motor speed control.
Motor speed controller uses high power MOSFET, fast PWM to achieve
efficiency 99% in most cases. Powerful microprocessor brings in
comprehensive and precise control to brushed motor controllers. This
programmable brushed motor controller also allows users to set
parameters, conduct tests, and obtain diagnostic information quickly and
easily.
Features:
•Opto-isolated technology achieves stability.
•Intelligence with powerful microprocessor.
•Synchronous rectification, ultra low drop, and fast PWM to achieve very
high efficiency.
•Current limit and torque control.
•Low EMC.
•LED fault code helps user debugging.
•Battery protection: current cut back, shutdown and warning at low
battery.
• Rugged aluminum housing for maximum heat dissipation.
•Thermal protection: Current cutback at low temperature and high
temperature to protect battery and controller.
•High pedal protection: Disable operation if power up with non-zero
throttle.
•Brake switch is used to start regen.
•0-5V brake signal is used to command regen current.
• PWMable Reverse Alarm.
• Brake Switch for regeneration.
• Analog Brake Input for continuous variable regeneration.
General Specifications:
•Frequency of Operation: 16.6kHz.
•Standby Battery Current: less than 1 mA.
•Supply Voltage, PWR, 8 to 30V.
•Supply Current, 200mA @ 12V, or 2.5W.
•Operating Voltage, B+, 18V to 180V.
•Analog Brake and Throttle Input: 0-5 Volts. Producing 0-5V signal with
3-wire pot.
•Reverse Alarm, Main Contactor Coil Driver, Meter.
•Full Power Temperature Range: 0℃ to 40℃ (controller case temperature).
•Operating Temperature Range: -30℃ to 90℃, 100℃ shutdown (controller
case temperature).
•Motor Current Limit,10 seconds boost: 500A
•Motor Current Limit, 1 minutes: 450A
•Motor Current Limit, continuous: 200A
