KDHE High Power PM Motor Speed Controller
Kelly KDHE programmable high power 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 98% in most cases. Powerful microprocessor brings in comprehensive and precise control to brushed motor controllers. This programmable PM brushed motor controller also allows users to set parameters, conduct tests, and obtain diagnostic information quickly and easily.
Features:
•Opto-isolated technology achieve 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.
•Easy installation: 1-4V "Hall Active" throttle or "3 Wire" potentiometer(<100K) can work.
General Specifications:
•Frequency of Operation: 16.6kHz.
•Standby Battery Current: less than 1 mA.
•Supply Voltage, PWR, 10 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 50℃ (controller case temperature).
•Operating Temperature Range: -30℃ to 90℃, 100℃ shutdown (controller case temperature).
•Motor Current Limit,10 seconds boost: 1200A
•Motor Current Limit, 1 minutes: 1100A
•Motor Current Limit, continuous:480A
Please note: 144V controllers generate large heat with high current. Need good size of heat sink and force air flow. Liquid cooling is preferred to get max power output.
