75 kW VFD for pump, fan, and compressor duty
The 6SL3220-2YD42-0UB0 is a SINAMICS G120XA variable-frequency drive rated 75 kW at 400 V in low-overload (LO) duty, drawing 136 A continuous. That LO rating means it handles constant-torque loads like conveyors or positive-displacement pumps without derating — the 150 A max output gives a 10 % headroom for short-duration overloads. Input accepts 380–440 V three-phase at 47–63 Hz, so it works on 50 Hz European or 60 Hz North American grids within the same unit. The 0.98 efficiency keeps power losses to 1.720 kW at full load — that's the heat the enclosure must vent, not a trivial number for a panel build.
Output frequency range and control modes
V/f control reaches 550 Hz output, suitable for high-speed spindles or centrifugal compressors. Vector control tops out at 240 Hz, which covers most standard AC induction motor applications up to 4-pole machines at 7200 RPM. Pulse frequency is set at 4 kHz by default — raising it quiets motor noise but derates output current. The power factor range of 0.75–0.93 (with offset cos φ 0.99) means the drive's input stage draws near-unity power factor across most of the load range, reducing reactive current on the supply transformer.
Lifecycle and sourcing reality
Estimated lead time is 1–10 working days on standard quantities. Sourced through independent distribution; availability and current pricing are confirmed at RFQ against the BOM quantity.
