Product Description:
The FC-102P37KT4E55H1XG is an AC variable frequency drive manufactured by Danfoss as part of the VLT FC 102 HVAC Drives series. Designed for building automation, the unit modulates the speed of induction motors used in fans, pumps, and compressors, allowing precise airflow or water circulation without mechanical throttling. Its design supports installation in air-handling units, chiller plants, and packaged rooftop equipment found in commercial facilities. Variable-speed operation also allows connected equipment to respond to changing demand instead of running continuously at full speed.
The inverter delivers a continuous shaft output of 50 hp, corresponding to a mechanical power rating of 37 kW. The input section accepts line voltages from 380–480 VAC and is configured for three-phase power, so it connects directly to compatible industrial mains without a transformer. Internal electromagnetic compatibility components provide an emissions limit classified as RFI Class A1/B (C1), supporting installations where conducted electrical noise must remain within Category C1 limits. The drive regulates motor voltage and frequency to adjust speed according to commands from the building control system. This control method is suitable for maintaining pressure, flow, or temperature as operating conditions change.
The housing has an enclosure rating of IP55 / Type 12, protecting the electronics from dust and low-pressure water jets when the cabinet door is closed. Local setup and monitoring are handled through the integrated graphical local control panel, which presents parameter menus, operating values, and trend readouts without requiring external software. The power stage has no brake chopper, so applications requiring regenerative braking must use an appropriate external braking method or mechanical control. Platform identifier 102 indicates compatibility with accessories and parameter sets intended for the FC 102 platform. The drive can receive control commands for common HVAC functions, including fan-speed regulation, pump control, and compressor operation.
