programmable sensorless BLDC motor controller provides efficient, smooth and quiet controls for fans, water pump, air-conditioning, compressor, etc. 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.

KSL controllers are produced for sensorless BLDC motors, especially for fans, water pump, air-conditioning, compressor, etc. 

Parameters should be set correctly before use!
