Product Description:

The FC-102P1K5T4E20H1XXXXXXSXXX is an AC variable frequency drive manufactured by Danfoss for the VLT FC 102 HVAC Drives series. Within air-handling units and chilled-water pump systems, the unit adjusts motor speed so that airflow or water flow follows real-time building demands. This variable-speed operation can improve energy efficiency and reduce mechanical wear in industrial and commercial automation systems. The drive provides a dedicated control platform for heating, ventilation, and air-conditioning equipment that requires responsive motor regulation under changing loads.

The power section accepts a line supply of 380 to 480 VAC delivered as three-phase power, matching common distribution voltages in mechanical-room panels. Its IP20 chassis protects against accidental finger contact while allowing cooling air to circulate when the drive is installed inside a suitable cabinet. The open chassis design requires an enclosure that provides appropriate protection from moisture, conductive debris, and direct contact with internal components. Conducted emissions are limited by the integrated RFI Class A1/B (C1) filter, allowing connection to compatible building power networks without a separate line filter. Field conductors enter through standard cable entries, simplifying gland-plate preparation while supporting the cable spacing needed for electromagnetic compatibility. The cabinet must provide adequate ventilation and clearance around the drive so that heat can leave the power electronics during continuous operation.

The drive has no brake chopper, so regenerative energy must be managed by the connected motor system or suitable external equipment when the application produces significant overhauling loads. The factory configuration includes no local control panel, making operator interaction dependent on a separately selected interface or remote control system. It also includes no optional line-supply hardware, so any additional input disconnects, fuses, or conditioning components must be provided elsewhere in the installation. The control boards use an uncoated printed circuit board design, which requires the cabinet environment to remain within the permitted humidity and contamination limits. No supplementary terminal blocks or conduit plates are preinstalled, allowing the standard cabinet cable arrangement to be used. These installation conditions are particularly important in mechanical rooms where condensation, dust, or airborne contaminants could otherwise reach exposed electronic assemblies.
