WEG CFW09 AC Variable Frequency Drives (1HP to 500HP)

CFW09 VECTRUE Inverter

The WEG CFW09 Series of Variable Frequency Drives incorporate the world’s most advanced technology in drives for three-phase AC induction motors. The Vectrue Technology™ represents a significant advancement, allowing this new generation of WEG VFD’s to combine V / F, Sensorless Vector and Closed Loop Vector (with encoder) control techniques all in one product. A WEG innovation simplified applications that require braking torque. Optimal Braking™ eliminates the need for the dynamic braking resistor in some applications allowing a simpler, more compact and economic solution.
