Product Description:

The FC-051P5K5T4E20H3BXC is an AC variable-frequency drive manufactured by Danfoss as part of the VLT FC 51 Micro Drives series. This compact inverter modulates motor speed by converting fixed mains power into a controlled output waveform, allowing conveyors, pumps, and small process machines to run at the speed required by the application. Variable-speed control can reduce mechanical shock during starts and stops and can also help match motor output to changing process demand. In distributed automation layouts, its size and chassis format make cabinet integration straightforward while still providing stable torque and speed regulation.

The drive supplies up to 5.5 kW of continuous electrical output. For users who prefer imperial units, the same output equals 7.5 HP. The input section is designed for line voltages from 380–480 VAC, so it can be wired directly to common industrial feeders. Its control electronics and output bridge are suited for a three-phase supply, eliminating the need for external phase-conversion hardware. The enclosure has an IP20 / Chassis rating, which provides finger-safe access to live parts but still requires panel installation in dusty or wet environments. This combination suits compact industrial systems that need reliable motor control without a large cabinet footprint.

A built-in brake chopper enables dynamic energy dissipation during rapid deceleration events, helping protect the DC bus and connected motor from overvoltage. Circuit boards use a coated PCB finish that resists airborne contaminants and humidity, which can extend service life in production areas with changing ambient conditions. Conducted emissions are reduced by the integrated filter that meets RFI Class A1/B, helping the system comply with EMC requirements without external line chokes. Operator access is limited because the model is supplied with no local control panel, so startup and parameter changes are carried out through remote fieldbus commands or a temporary pluggable keypad. This arrangement suits installations where routine control is handled from a higher-level system rather than from the drive face.
