Product Description:

The FC-051P1K5T4E20H3BXC is an AC variable-frequency drive produced by Danfoss for the VLT FC 51 Micro Drives series within the VLT Micro Drive product group. This compact inverter converts fixed mains power into a modulated electrical output that allows control systems to vary the speed and torque of an induction motor. Its small footprint makes it suitable for pumps, fans, conveyors, and other motor-driven equipment installed in space-limited industrial panels. The drive can regulate motor operation according to process demand, reducing unnecessary mechanical output when full speed is not required.

The drive accepts a supply range of 380–480 VAC on a three-phase network, allowing direct connection to common industrial power systems without a transformer. Its continuous mechanical output is rated at 1.5 kW, which corresponds to 2.0 HP. This output capacity supports small and midsize motors used in material-handling, ventilation, and fluid-control applications. The internal radio-frequency suppression meets RFI Class A1/B, limiting conducted electrical interference on connected power lines. The Micro Drive Series 051 platform uses a common parameter structure that supports consistent configuration across compatible units.

The chassis has an IP20 protection rating, so the drive must be installed inside a suitable enclosure where dust, moisture, or accidental contact may be present. Dynamic stopping energy is managed through an integrated brake chopper, which controls the connection to a compatible braking resistor when rapid deceleration is required. The control board uses a coated printed circuit board that helps protect conductive traces against humidity, dust, and corrosive airborne contaminants. The unit includes no local control panel, so parameter adjustments and operating commands require a compatible remote keypad or communication connection. Omitting the local panel reduces the space required at the front of the drive and limits direct access to operating settings. The enclosure should provide adequate ventilation around the chassis so internally generated heat can leave the drive during continuous motor operation.
