Product Description:

The FC-051P5K5T4E20H3BXCXXXSXXX is an AC variable frequency drive from Danfoss that belongs to the VLT FC 51 Micro Drives series. It regulates induction motor speed so conveyors, pumps, and small process machines can match changing load demands instead of operating continuously at the mains frequency. This speed regulation can reduce unnecessary motor operation while providing controlled acceleration and deceleration. The compact chassis is intended for control cabinet installations where panel depth is limited, allowing speed control to be added without extensive enclosure modifications.

The drive provides a motor output of 5.5 kW, corresponding to a mechanical shaft capability of 7.5 HP. It accepts an input voltage range of 380–480 VAC from a three-phase network, making it suitable for common industrial power systems without an autotransformer. Motor terminals and control electronics are contained within a housing with an IP20 chassis protection rating. This enclosure protects against accidental contact with internal electrical parts but does not provide complete protection against dust or water. The drive must therefore be installed inside a suitable ventilated cabinet. Its compact format helps conserve mounting space alongside contactors, circuit protection devices, and other control equipment.

Electromagnetic emissions are limited by an integrated RFI Class A1/B filter, reducing the need for separate filtering components in compatible installations. For dynamic deceleration, a built-in brake chopper directs regenerated energy to an appropriately selected external braking resistor. A protective PCB coating shields the control circuitry from humidity and airborne contaminants that may enter the cabinet. Field wiring passes through standard cable entries, providing conventional routing for power and control conductors. The configuration does not include a mains disconnect, so supply isolation must be provided separately within the electrical installation. It also does not include a local control panel, which means operating commands and parameter access require a remote control arrangement or another compatible interface.
