Product Description:
The FC-280PK55T4E20H1 is an AC variable frequency drive produced by Danfoss for the VLT FC 280 series. The drive converts fixed-frequency line power into a pulse-width-modulated output, allowing a PLC or HVAC controller to adjust motor speed according to the operating load. Typical applications include circulating pumps, supply-air fans, and light conveyor sections that require efficient variable-speed operation. The drive uses open-loop V/Hz regulation for applications that do not require closed-loop position or velocity feedback.
Its motor output is rated at 0.55 kW, which corresponds to a mechanical shaft capability of 0.75 HP. This power range is suitable for equipment that operates below one mechanical horsepower under continuous rated conditions. The input rectifier accepts three-phase power from 380 to 480 VAC, allowing connection to common industrial power systems without a step-up or step-down transformer. The IP20 housing protects against finger contact with internal components but requires installation inside a ventilated control cabinet. Cabinet ventilation must provide adequate airflow around the drive so that heat from the power electronics can dissipate during continuous operation.
The chassis mounting format positions the heat sink in line with cabinet airflow channels and supports compact panel installation. Placement in the Midi Drive FC product group indicates a design focused on essential motor speed-control functions. Regenerative hardware is not included, which helps reduce the enclosure depth for installations where returned braking energy does not need to be recovered. Conducted emissions are reduced by an integrated filter that meets EMC Category C1 at 200 V or Category C2 at 400 V. This filter reduces the need for separate suppression components and leaves more DIN-rail space available for contactors, circuit protection, and control relays. The filtered design also supports installation near low-level analog and communication wiring when proper cable routing and grounding practices are followed.
