Product Description:

The FC-280PK55T4E20H2BXCXXXSXXXXAX is an AC variable-frequency drive produced by Danfoss for the VLT FC 280 Midi Drives series. It is sized for decentralized cabinets where space and thermal loading are limited, and it converts constant-frequency mains power into an adjustable output for controlled motor operation. This allows packaging machines, light conveyors, and ventilation fans to run only as fast as required by the control program. A chassis-mount housing supports installation inside an enclosure, and the parameter structure matches related drives in the series for consistent setup.

The drive’s continuous output capability is rated at 0.55 kW, which suits fractional-kilowatt motors commonly used in auxiliary axes. It accepts a three-phase 380-480 VAC supply, so it can connect to standard industrial mains without a transformer. For applications that use mechanical horsepower, this output also corresponds to 0.75 HP. The enclosure is rated IP20 / Chassis, which helps guard live parts from accidental finger contact while still requiring the surrounding enclosure to provide protection against dust and moisture. Conducted emissions are reduced by an integral RFI filter rated EMC Cat C3 (200/400V), which supports compliance on installations that use longer motor cables.

Dynamic braking energy is handled by an internal brake chopper, allowing the motor to decelerate quickly without overvoltage trips on the DC bus. Reliability in harsh shop-floor air is supported by a coated PCB, which helps resist moisture and airborne contaminants inside the cabinet. Command signals reach the inverter through a standard control card with Modbus, enabling direct serial communication with PLCs for setpoint changes and diagnostics. Local parameter editing is omitted because the front panel has no display, so adjustments are made with a remote keypad or a fieldbus tool while the compact housing depth is maintained.
