Kelly KHB14301,24V-144V,300A,BLDC Controller /Regen

Quick Overview

Kelly KHB opto-isolated BLDC motor controller provides efficient, smooth and quiet controls for electric motorcycle, forklift, hybrid vehicle, electrical vehicle, electric boat, as well as industry motor speed or torque control. Motor speed controller uses high power MOSFET, PWM to achieve efficiency 99% in most cases. Powerful microprocessor brings in comprehensive and precise control to BLDC motor controllers. This high power programmable brushless motor controller also allows users to set parameters, conduct tests, and obtain diagnostic information quickly and easily.
