KBS-X - Mini Brushless Motor Controller (12V-72V) (25A-55A)

Kelly KBS programmable BLDC motor controller provides efficient, smooth and quiet controls for electric motorcycles, golf carts, go-carts, as well as industry motors 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.
