Product Description:
The 131U3961 is a variable-frequency drive produced by Danfoss for the VLT FC 302 Automation Drives series. In automated facilities, it regulates the speed of AC induction motors, letting conveyors, pumps, or fans follow changing process demands instead of running at a fixed frequency. The drive can be installed in decentralized or cabinet-mounted control panels, and it uses the fieldbus accessories common to other FC 302 units. That arrangement supports variable-speed duties where motor output must match line conditions, flow requirements, or changing material loads.
Electrically, the drive is built for three-phase power systems, accepts 380–500 VAC mains, and can supply 55 kW or 75 HP to the motor. A built-in brake chopper dissipates regenerated energy during fast stops to help prevent DC-link overvoltage. Normal cabinet-mount A, B, and C frames ease enclosure layout, and standard cable entries maintain strain relief. Conformal-coated PCBs resist airborne moisture and dust. The adaptation slots are factory blank, and options A, B, C, C0, C1, D, and the mains option are unused. Series identifier 302 and the standard language pack keep menu structure and display text consistent across related drives.
Thermal and electromagnetic stability are addressed by the IP20 chassis housing and an integrated RFI filter, so the drive can sit near sensitive PLC modules without excessive interference. Operators interact through a graphical local control panel, which displays parameters and status messages in multiple languages during setup and operation. The front interface also allows local viewing of alarms, operating values, and parameter names without external accessories. For applications needing precision speed feedback, the factory-installed MCB-103 resolver option supplies high-resolution rotor data to the control algorithm. All auxiliary slots are empty at delivery, so the standard configuration remains open for integration into automation cabinets.
