Product Description:

The FC-102P22KT4E55H2XGXXXXSXXXXAXBXCXXXXDX is an AC variable frequency drive manufactured by Danfoss for the VLT FC 102 HVAC Drives series. It regulates the speed of three-phase induction motors in air-handling units, pumps, and cooling towers, allowing building automation controllers to match motor output to changing load demands. This speed control can reduce energy consumption during periods when the connected equipment does not need to operate at full capacity. The drive can be mounted as a stand-alone cabinet component in mechanical rooms or installed within suitable control panels.

The inverter delivers a continuous motor output of 22 kW, equivalent to 30 HP, for medium-sized fan sections and chilled-water pumps. Its input section accepts line voltages from 380–480 VAC on a three-phase power network, eliminating the need for step-up transformers on compatible industrial mains. The enclosure has an IP55 / Type 12 rating, protecting internal components against dust, dripping water, and light exposure to plant-room contaminants. This enclosure allows wall or frame mounting in appropriate areas outside dedicated switchgear rooms. The integrated DC bus does not include a brake chopper, so rapid deceleration requires the system to dissipate regenerated energy through motor losses or suitable external equipment. The printed circuit boards are uncoated, while temperature-based derating routines help protect the drive from excessive thermal loading.

Electrical wiring passes through standard cable entries, providing conventional routes for mains, motor, and control conductors. Electromagnetic interference on public power networks is reduced by the built-in RFI filter, which helps limit conducted noise from the inverter switching stage. Local access is provided through the graphical local control panel, which supports start and stop commands, parameter editing, operating-status review, and real-time fault-code display. Its graphical interface presents drive information in multiple languages through the standard language pack. Remote control signals can be supplied by a building automation controller, allowing motor speed to respond to pressure, temperature, flow, or other process demands. Service connections support access to operating parameters and diagnostic information when configuration changes or fault analysis is required.
