Product Description:

The FC-051PK75T4E20H3XXCXXXSXXX is an AC variable frequency drive produced by Danfoss for the VLT FC 51 Micro Drives series. Designed for cabinet installation, the unit controls the speed of small three-phase induction motors, allowing automated equipment to match motor torque and speed to changing process demands. Its compact format reduces the panel space required for installation in material-handling lines, process skids, and HVAC systems. The drive provides motor control functions in a small enclosure suited to applications with limited cabinet space.

The drive delivers a continuous output of 0.75 kW, which is equivalent to 1.0 HP, making it suitable for small pumps, fans, and conveyors. It accepts a supply voltage of 380-480 VAC from a three-phase network and uses pulse-width modulation to generate the commanded motor frequency. Heat is conducted through the chassis, while the open-sided enclosure has an IP20 chassis rating and must be installed in a closed panel when protection from dust or liquids is required. The drive does not include an internal brake chopper, so regenerative energy produced during rapid deceleration must be managed by external equipment. A mains option is not installed, which leaves the incoming power connection in its basic configuration.

Conducted electrical noise is reduced by an integrated RFI Class A1/B filter, eliminating the need for a separate filter module in suitable installations. The control electronics use a coated PCB that resists moisture and airborne contaminants in industrial cabinets. Wiring passes through standard cable entries that align with compatible metric gland plates and support organized cable routing. A local control panel is not installed, so parameters must be accessed through a remote communication link or an optional keypad. The enclosure and electrical arrangement use the standard configuration for this model without special adaptations.
