What this drive delivers on a 480V line
The Delta VFD5A7MH43ANSAA sits in the 480V class at Frame C, sized to a 3.7 kW / 5 HP motor with a 10.5 A rated output — so it covers the typical mid-range induction motor on a 3-phase 380–480V supply without stepping up to a larger chassis. Heavy Duty is set at 9.9 A input and Normal Duty at 11.6 A input, with 8.0 KVA rated output capacity — the Normal Duty figure is the ceiling when the load profile is steady (fans, centrifugal pumps), and the Heavy Duty figure is what governs constant-torque loads like conveyors or positive-displacement pumps.
Operating envelope and panel-side behaviour
Carrier frequency is adjustable from 2 to 15 kHz with a 4 kHz factory default — pushing it toward 15 kHz quiets motor whine but pulls continuous output current down on the derating curve, so any acoustic upgrade has to be re-checked against the motor nameplate FLA. Cooling is natural convection on a Frame C chassis at IP20 — the drive relies on clean cabinet airflow and panel clearances per the installation drawing; an IP20 / open-chassis unit is not a sealed field-mount, so the enclosure (not the drive) carries the wet- or dust-side rating.
Sourcing reality and lifecycle read
EMC filter is optional on this build, which means cabinet-side filtering (line reactor, footprint filter) is a separate BOM line when the installation requires it.
Where this drive lands in the same 480V family
Within the Delta 480V M-series the next step up — Frame D at 14.5 A output, 5.5 kW / 7.5 HP, normal duty 16.0 A — is a different chassis size and a different current rating, so it does not drop into a panel cut-out or wiring layout built around this Frame C without mechanical rework.
