Product Description:

The FC-280PK75T4E20H1BXCXXXSXXXXA0 is a variable frequency drive produced by Danfoss for the VLT FC 280 Midi Drives series. It converts fixed-frequency mains power into a controlled output waveform so connected motors can run at the speed required by the process instead of operating only at full line frequency. This makes the unit suitable for pumps, blowers, and conveyors where stable speed control, reduced mechanical stress, and efficient operation are important in everyday industrial use.

This model provides a continuous output rating of 0.75 kW, which corresponds to 1.0 HP. The input section accepts three-phase 380 to 480 VAC, allowing connection to common industrial power systems without a separate transformer. Dynamic braking energy is handled by a built-in brake chopper, which helps control DC-bus voltage during deceleration. The enclosure is an IP20 chassis type, so the drive is intended for installation inside a suitable control cabinet where the surrounding equipment provides additional protection. Conducted emissions are reduced by an integrated EMC Category C1 (200 V) / C2 (400 V) RFI filter, helping the installation meet interference limits with fewer external components.

Communication is handled by an integrated Profibus DP control card, allowing cyclic command exchange and status reporting with compatible PLC-based automation systems. Long-term durability is improved by a coated PCB, which helps protect the circuitry from moisture and conductive dust in demanding cabinet environments. The chassis-mounted format supports compact panel layouts, and the drive can regulate motor speed smoothly across applications that require repeatable torque control. Its operating concept is well suited to machinery that needs responsive acceleration and deceleration while maintaining consistent process behavior during normal production.
