Sizing a 7.5 kW motor on a 460 V bus
The VFD075M43A sits in the Delta VFD-M micro-drive family and is sized for a 7.5 kW / 10 HP motor on a 3-phase 460 V supply — rated output current is 18 A with a rated output capacity of 13.7 kVA, so it covers the standard induction-motor envelope for that power class without step-up. Input accepts 3-phase 380-480 VAC at 50/60 Hz with ±10% voltage tolerance (342-528 VAC) and ±5% frequency tolerance (47-63 Hz), drawn at 23 A rated input current; the wide input window lets the same drive ride plant-voltage sag and generator-supplied panels without an external transformer.
Output range, carrier, and where it fits in a panel
Output frequency spans 0.1-400 Hz, meaning the drive handles both low-speed high-torque fans and high-speed spindle-style loads up to that ceiling; the maximum output voltage tracks the input proportionally, so a 380 V plant delivers a 380 V motor-side waveform. Carrier frequency is adjustable from 1-15 kHz — pushing it up quiets motor acoustic noise but increases switching losses, so the installer trades acoustic comfort against thermal headroom per the drive's derating curve.
Where it sits in the VFD-M current ladder
Within the VFD-M Series the VFD075M43A is the 7.5 kW rung on the 460 V class — the lighter siblings in the same voltage class are VFD007M43B at 0.75 kW / 1 HP with 3 A output and VFD015M43B at 1.5 kW / 2 HP with 4 A output, while VFD022M43B at 2.2 kW / 3 HP with 5 A output sits between them; each step roughly doubles or halves the current rating, so the right drive is the one sized to the motor nameplate rather than the nearest catalog match.
