Product Description:
The FC-051P7K5T4E20H3B is a Danfoss drive that belongs to the VLT FC 51 Micro Drives series. As a compact micro drive, it is installed in control cabinets to adjust induction motor speed and torque so that small conveyors, pumps, or fans can follow process demands rather than running at a fixed utility frequency. The compact housing is suited to industrial automation systems where panel space is limited, while its motor-control capabilities allow equipment output to be adjusted for changing operating conditions.
The drive delivers a continuous mechanical output of 7.5 kW, which corresponds to 10 HP when U.S. customary units are required by plant documentation. It connects directly to utility grids rated at 380–480 VAC, eliminating external transformers in installations that provide a compatible supply. Internal rectification and pulse-width modulation inversion are designed for a three-phase mains input, so balanced line conductors are required for full-power operation. The enclosure has an IP20 chassis protection rating, providing protection against accidental contact with live parts but no sealing against dust or liquids. The drive must therefore be installed inside a suitable control cabinet with adequate ventilation and protection from contaminants. Proper cabinet airflow also helps remove heat generated by the power electronics during sustained motor operation.
A built-in brake chopper routes surplus DC-bus energy to an external resistor, allowing rapid deceleration without tripping the overvoltage threshold. Radio-frequency emissions are suppressed by the integrated RFI Class A1/B filter, which helps the panel meet applicable electromagnetic compatibility limits without additional line-side filtering in suitable installations. The internal control platform belongs to Micro Drive Series 051, which uses a common parameter structure across related models in the series. The VLT Micro Drive product group supports compatible mechanical accessories, including busbars and keypad extensions, across multiple frame sizes in the same lineup. These interfaces allow the drive to be integrated with common control-panel wiring arrangements and external braking components. Installation clearances and external resistor selection should follow the applicable operating instructions for the selected motor load and cabinet arrangement.
