Product Description

High Efficient KDH72801E,24-72V,800A PM with Regen


 KDHE High Efficient 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.
