KDHD High Power Series/PM Motor Speed Controller
Kelly KDHD 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
