Kelly KBS-E Controllers User Manual
KBS BLDC Motor Speed Controller
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.
Provide free male or female connectors matching with KBS controller.
