Product Description:

The FC-102P3K0T4E20H1XGXXXXSXXXX is an AC variable frequency drive manufactured by Danfoss as part of the VLT FC 102 HVAC Drives series. Classified within the VLT HVAC Drive product group, it is intended for fan, pump, and compressor circuits where proportional speed control can reduce energy demand and operating noise. By converting fixed-frequency, three-phase mains power into a variable-frequency output, the drive allows building management systems to adjust airflow and water circulation according to real-time thermal loads. This control method reduces reliance on dampers, control valves, and other forms of mechanical throttling.

The power section accepts a mains voltage range of 380–480 VAC and operates on three-phase power, allowing connection to common industrial electrical feeds without a transformer. The enclosure provides IP20 chassis protection and is intended for installation inside a suitable electrical cabinet. Local setup and operation are handled through a front-mounted graphical local control panel, which provides parameter menus, trend information, and manual start and stop controls. Incoming power and motor conductors use standard cable entries, simplifying gland plate preparation when several drives are installed in a switchboard. The printed circuit boards are uncoated, so the installation must protect the unit from condensation and corrosive airborne contaminants. No mains option is installed, and Adaptation A retains the standard cable-entry arrangement for the applicable frame.

An integrated RFI Class A1/B (C1) filter reduces conducted electrical noise on the incoming supply lines. The drive has no brake chopper, so applications requiring rapid deceleration must manage regenerated energy through the motor, the mechanical load, or suitable external equipment. Control functions operate with the latest standard software release, while the standard language pack provides access to menus in multiple supported languages. Adaptation B is set to no adaptation, which retains the base mechanical outline for this configuration. The chassis design relies on cabinet airflow to remove generated heat, so the installation must provide the clearances and ventilation required for stable operation. Its front controls provide direct access to operating status, parameter changes, and manual commands without requiring a separate display device.
