Kelly KBS Controllers User ManualX:The enhanced version of KBS-L.
KBS BLDC Motor Speed Controller
Kelly KBS programmable BLDC motor controller provides efficient, smooth and quiet controls for electric motorcycle, golf cart, go-cart, 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 programmable brushless motor controller also allows users to set parameters, conduct tests, and obtain diagnostic information quickly and easily.
Provide free male or female connectors matching with KBS controller.
