Product Description:

The FC-103P15KT4E20H2XGXXXXSXXXXAXBXCXXXXDX is a variable frequency drive manufactured by Danfoss for the VLT FC 103 Refrigeration Drives series. It modulates the speed of induction motors used in compressors, condensers, and evaporator fans so that cooling capacity tracks the thermal load in industrial refrigeration systems. By varying output frequency rather than relying on mechanical throttling, the drive can reduce unnecessary energy consumption and mechanical wear in automated cold-chain equipment. Its refrigeration-oriented parameter sets support motor control in ammonia, CO2, and HFC-based installations. The drive can regulate compressor and fan operation as cooling demand changes, helping the connected system maintain stable temperatures under varying loads.

The drive provides a continuous motor output of 15 kW. Its input section accepts 380–480 VAC from a three-phase supply, allowing operation from common industrial power networks without a step-down transformer. Heat is transferred through the metal chassis, and the IP20 chassis must be installed inside a suitable control panel that prevents contact with internal electrical components. The unit has no brake chopper, so applications requiring dynamic braking must use compatible external equipment. A mains disconnect is also not integrated into the drive, leaving supply isolation to the surrounding electrical installation. The printed circuit boards are not coated, so the installation area should remain free from condensation, corrosive fumes, and excessive airborne contamination.

The enclosure uses standard cable entries to provide straightforward routing for incoming power, motor, and control wiring. A built-in graphical local control panel provides access to operating parameters, status information, and real-time feedback without requiring a separate display. Conducted electrical emissions are reduced by an RFI filter rated for Class A2, supporting use in industrial environments where category C2 limits apply. External electromagnetic compatibility components may still be required when cable lengths, grounding arrangements, or site conditions exceed the filter’s intended operating range. Optional input/output, motion-control, and adaptation modules are not installed, so any additional control functions must be provided through compatible external components or separately selected drive accessories. The open chassis arrangement allows cabinet airflow to remove heat while the surrounding panel provides the required physical and environmental protection.
