131H2939

Product Description:

The 131H2939 from Danfoss stands as a solid choice in the VLT FC 302 Automation Drives family, packing in a rated 75 kW (100 HP) power output and geared for demanding automation. The build fits a chassis-protected IP20 enclosure, which sets a clear boundary for where it should operate since it handles indoor installations best—common for a lot of inverter types. Input runs on 480 V AC three-phase, and output matches that same voltage rating. Current moves through at a steady 130 A, so control panels with bigger loads link up without requiring adapters or odd tweaks.

There’s an integrated RFI filter already installed to keep radio frequency interference in check, so nearby electronics or sensors don’t skip or misread during use. The drive slot fits a C4 frame size; not too bulky, not compact, a mid-range chassis usually called up in medium-sized manufacturing lines or heavy processing. The frequency control range starts all the way down at zero and rolls up to 590 Hz, which makes custom motor speeds simple to dial in. Onboard, a brake chopper with IGBT support is already included. Support for constant torque and a protected temperature threshold (no derating needed up to 50°C) help in big-volume rooms or a messier workspace where airflow isn’t perfect.

Installation wiring matches straight up for industrial automation jobs, since input and output voltages pair up nicely, and sturdy Danfoss terminals cut down on the risk of loose fits. The layout and label markings show information clearly without hunting through manuals, so swap-outs go faster. In setups that care about reliability and tight speed control, the VLT FC 302 handles long running shifts, sudden stops, or stepwise speed changes without drama.
