Product Description:

The FC-103P45KT4P21H1XGCXXXSXXXXAZBXCXXXXDX is a frequency converter produced by Danfoss as part of the VLT FC 103 Refrigeration Drives series. This AC drive is engineered for variable-speed control of compressors, condensers, and evaporator fans in supermarket cases, cold rooms, and process chillers. By matching motor speed to instantaneous load, it cuts energy draw, soft-starts equipment, and stabilizes suction pressure. The device belongs to the VLT Refrigeration Drive product group and is delivered on a Type 1 backplate for mounting inside standard electrical enclosures.

Rated for a mains supply of 380 – 480 VAC, the drive accepts a three-phase input and delivers up to 45 kW of continuous output power, which is equivalent to 60 HP at the motor shaft. The backplate housing carries a protection level of IP21 / Type 1 backplate, allowing installation in dry indoor panels without extra gasketing. Standard cable entries are provided under Adaptation A to simplify wiring. Because a brake chopper is not included, any regenerative energy returning from the motor must be handled by external components during deceleration. The printed circuit boards are conformally coated, and an internal RFI filter limits conducted emissions to Class A1/B. A standard language pack is preloaded for multilingual menu access.

The A-Option slot contains the AK-LonWorks MCA 107 card for networked building-management control. A graphical local control panel shows parameters, status information, and real-time values without external tools. Conducted noise is further suppressed by the integrated Class A1/B RFI filter, keeping the installation within typical commercial limits. Long-term reliability in humid plant rooms is supported by the coated PCB finish. No B-option, C-option, C0-option, C1-option, D-option, or mains option is fitted.
