The Delta VFD-E VFD075E43A is a 7.5 kW (10 HP) sensorless vector AC motor drive (variable frequency drive) for controlling the speed of three-phase AC induction motors. It runs from a 3-phase 380-480 V, 50/60 Hz supply and delivers a three-phase 0-480 V output rated at 18 A, with a built-in brake chopper in an IP20 enclosure.
