Product Description:
The FC-103N355T4E20H4XGCXXXSXXXXAXBKCXXXXD0 is a Danfoss variable-frequency inverter supplied under the VLT FC 103 Refrigeration Drives series. It regulates the speed of induction motors used with compressors, pumps, and evaporator fans in cold-storage and process-chilling installations. By matching motor speed and torque to the cooling load, the inverter reduces unnecessary energy consumption during periods of lower demand. Controlled acceleration and deceleration also reduce mechanical stress on connected refrigeration equipment and help prevent abrupt pressure changes within the system.
This model delivers 500 HP of mechanical output and has an electrical power rating of 355 kW. The power section accepts a three-phase supply ranging from 380–480 VAC. Its three-phase input allows direct connection to compatible industrial power systems without phase-conversion equipment. The IP20 chassis protects against accidental contact with internal components, but the drive requires a suitable ventilated cabinet where dust or liquid exposure may occur. A built-in Class A1 RFI filter limits conducted electromagnetic interference on the incoming power line. During a loss of line power, the 24 V DC backup keeps the control electronics active so the refrigeration system can perform an orderly shutdown.
The drive includes a Graphical Local Control Panel with a high-contrast display and keypad for viewing operating data, adjusting parameters, and accessing diagnostics. Its printed circuit boards have a protective coating that improves resistance to moisture and chemical contaminants commonly present in refrigerated environments. An MCB-101 general-purpose I/O module expands the available control connections for external sensors, relays, and automation signals. Standard cable entries support straightforward routing through the gland plate and help organize power and control wiring inside the enclosure. The drive does not include a brake chopper, motion-control option, harmonic filter, or mains option, so those functions must be provided separately if the application requires them.
