WEG CFW900 Series AC Inverter for 18.5kW 400V 3 Ph motor to 40A at high overload, or 22kW to 50A when Fan/Pump rated. Operates in VxF, Sensorless Vector or Full Closed-loop Flux Vector (with encoder card fitted). Converts fixed frequency three phase 400V input to variable frequency three phase 400V to control the speed of a standard AC induction motor or PM synchronous motor.
