Product Description:

The FC-102P1K5T4E20H1XXXXXXSXXXXAXBXCXXXXDX is a variable frequency drive manufactured by Danfoss for the VLT FC 102 HVAC Drives series. In building automation, it regulates the speed of centrifugal pumps, fans, and compressors so energy use can follow real-time demand instead of forcing motors to run continuously at line frequency. By converting fixed mains power into a programmable output, the unit helps control systems maintain airflow, pressure, and temperature with tighter accuracy and reduced mechanical wear. This operating method can also reduce abrupt starts and support smoother part-load operation in HVAC equipment.

This model accepts a nominal input of 380 – 480 VAC delivered as three-phase power, so it connects directly to common industrial feeders without transformers. The chassis protection rating is IP20 / Chassis, which provides finger-safe terminals but still requires installation inside an enclosure where dust or moisture may be present. An integrated electromagnetic filter meets RFI Class A1/B (C1) limits, helping facilities comply with conducted-emission requirements on public low-voltage networks. Wiring enters through standard cable entries, which simplifies gland plate selection and avoids custom knockouts. Because the electrical interface follows common HVAC panel practice, the drive can be integrated into building control cabinets without unusual supply or cable-routing provisions.

There is no local control panel, so parameter access relies on remote fieldbus connections or PC-based tools. This arrangement suits centrally supervised installations where operating data and settings are managed from a building controller rather than from the drive face. The control boards use an uncoated PCB, so the cabinet should protect the electronics from corrosive atmospheres. Mounting follows normal cabinet mounting for A, B, and C frames, which aligns the heat sink with standard rail spacing and airflow paths. The drive includes the latest standard software release, which provides updated motor-control algorithms and HVAC functions such as flow optimization and automatic energy reporting.
