Product Description:

The Danfoss 131N4631 is an AC variable-frequency drive supplied under the VLT FC 302 Automation Drives series. It converts fixed three-phase mains power into a variable electrical output for induction motors. The adjustable output regulates motor speed and torque in conveyors, pumps, and other automated equipment. This electronic control can replace mechanical throttling where the connected process requires changes in speed or flow.

The unit operates on three-phase power and delivers a rated shaft output of 45 kW, which corresponds to 60 HP. When supplied with 575 V, its apparent input demand is 61.7 kVA. The drive supports a continuous current of 62 A and a short-term overload current of 93 A. A brake chopper handles regenerated energy during motor deceleration, while the graphical local control panel provides direct access to operating parameters. The drive includes the standard language pack, and its internal series identifier is 302 within the VLT AutomationDrive FC product group. No RFI filter is installed, and the printed circuit board is uncoated. All expansion positions, including the A, B, C, C0, C1, D, and mains slots, are unpopulated. Adaptation B is configured without an adaptation, providing the baseline drive arrangement.

Power loss at nominal load amounts to 900 W, which must be considered when planning enclosure cooling and ventilation. The enclosure carries a protection rating of IP54/Type 12 N3R, protecting the electronics from dust and splashed liquids while permitting sheltered outdoor service. The housing measures 308 mm wide and 311 mm deep, with an overall height of 685 mm. Its gross shipping mass is 42.74 kg, while its installed mass is 39.74 kg. These separate mass values support transportation and mounting calculations without describing the same operating condition. Standard cable entries accept metric glands for mains, motor, and input/output conductors without increasing the required panel depth.
