Product Description:

The FC-103P15KT4P21H1XGCXXXSXXXXAZBXCXXXXDX is an AC variable-frequency drive manufactured by Danfoss for the VLT FC 103 Refrigeration Drives series. In industrial cooling systems, it regulates induction-motor speed so compressors, condensers, and evaporator fans can respond to changing thermal loads. Variable-speed operation can reduce unnecessary energy consumption and limit the mechanical stress associated with frequent starting and stopping. The drive also provides controlled acceleration and deceleration for refrigeration equipment that must operate across a broad range of demand conditions.

This model connects to a 380–480 VAC mains source through a three-phase supply. It delivers a continuous mechanical output of 15 kW, corresponding to 20 HP for compatible motors and loads. Its IP21 / Type 1 backplate enclosure supports panel mounting in indoor electrical rooms where protection against limited dripping water and accidental contact is required. Conducted emissions are attenuated by the built-in RFI filter, Class A1/B, supporting use on typical industrial power networks without a separate radio-frequency interference filter. The printed circuit boards have a protective coating that improves resistance to moisture and airborne contaminants in humid machine rooms. The drive does not include a brake chopper, so applications requiring rapid deceleration must use a suitable external braking arrangement or allow the connected load to decelerate naturally. Standard cable entries provide organized access for mains, motor, and control wiring.

Field integration is supported by the AK-LonWorks MCA 107 communication card, which allows operating data and commands to be exchanged with compatible building-management controllers. The card enables network supervision of refrigeration equipment without requiring each drive to be managed solely through local controls. A coated PCB assembly protects internal electronics from moisture and airborne contaminants that may be present around industrial cooling equipment. Operators enter parameters and review alarms through the graphical local control panel, which presents drive information in a readable menu format. The standard language pack provides multilingual menu and alarm text for facilities that use more than one operating language. The control interface provides access to motor settings, operating limits, status information, and diagnostic records used during routine system operation.
