LS Industrial Systems Starvert iS7 series AC Inverter for 18.5kW (25HP) 400V 3 Ph motor to 39A at high overload, or 22kW (30HP) to 45A when Fan/Pump rated. Operates in VxF, Sensorless Vector or Full Closed-loop Flux Vector (when the optional Encoder Feedback card is fitted). Converts fixed frequency three phase 400V input to variable frequency three phase 400V to control the speed of a standard AC induction motor.
