Product Description:

The FC-051P2K2T4E20H3BXCXXXSXXX is a compact AC variable-frequency drive produced by Danfoss and included in the VLT FC 51 Micro Drives series. It is intended for panel mounting and is used to regulate the speed of small three-phase induction motors in conveyors, pumps, and other general-purpose machinery. By varying output frequency and voltage, the drive provides adjustable motor speed without relying on mechanical throttling. Its compact format supports installations where cabinet space is limited, while still giving the motor controlled acceleration and speed regulation during operation.

The drive can deliver up to 3.0 HP of motor output, which corresponds to a continuous power rating of 2.2 kW. It accepts an input supply of 380–480 VAC and operates on a three-phase power supply, which suits common industrial electrical systems. The enclosure has IP20 chassis protection, which helps prevent accidental finger contact with internal live parts but is intended for installation inside a clean control cabinet. The standard cable-entry arrangement supports straightforward wiring, and the unit is built without a mains option card. Because the design is compact, it fits applications that need basic speed control without a large operator interface on the front of the drive.

The unit includes an integrated brake chopper to handle regenerated energy during deceleration, which helps support faster stopping without overloading the DC bus. Its control board uses a coated PCB, providing added resistance to moisture and airborne industrial contaminants inside the enclosure. An internal RFI Class A1/B filter reduces conducted emissions on the supply lines and helps the drive operate more cleanly near other electrical devices in the same cabinet. The design includes no local control panel, so operation and parameter changes are handled through remote control wiring or a service interface. This arrangement keeps the front of the unit simple and preserves the small footprint of the drive.
