Product Description:

The 131U4000 AC drive is produced by Danfoss for the VLT FC 302 Automation Drives series. It belongs to the VLT AutomationDrive FC product group and is intended to regulate motor speed in automated process lines, material-handling cells, and machine tools. Its role is to vary motor frequency and voltage so connected equipment can match process demand instead of running at a fixed speed. Installation is intended for cabinet mounts in A, B, and C frames, and the unit is used as an open-chassis component inside an electrical cabinet. This layout suits enclosed control cabinets where airflow and physical protection are provided by the surrounding enclosure.

The drive delivers a continuous output of 15 kW, which is equivalent to 20 HP for medium-duty pumps, fans, and conveyors. It accepts an input supply of 380–500 VAC on a three-phase power network, so it can connect directly to common industrial feeders. This input range supports use on standard industrial distribution systems without requiring a special supply arrangement. The enclosure is rated IP20, which provides touch-safe terminals but still requires cabinet installation where dust or liquids are present. Standard cable entries support line and motor wiring, and a brake chopper is not integrated, so dynamic braking must be handled externally when it is needed.

An integrated RFI filter reduces conducted emissions on the input side. The control interface uses a numerical local control panel for plain-text parameter entry and basic diagnostics, so routine setup information can be viewed directly on the drive. Feedback can be added through the factory-installed MCB-103 resolver option, while no A, C0, C1, or D options are fitted and no adaptation B or mains option is included. The printed circuit boards are not coated, so the drive is best suited to clean electrical rooms and enclosed cabinets with controlled conditions.
