Product Description:

The FC-280PK55S2E20H is a variable frequency drive manufactured by Danfoss within the VLT FC 280 Midi Drives series. The device serves as a compact speed controller for low-power AC motors used in general-purpose industrial automation. By modulating output frequency and voltage, it allows production equipment such as conveyors or process pumps to match motor speed with load demand while operating from a single-phase utility supply.

The drive has a power rating of 0.55 kW, equivalent to 0.75 HP, making the unit suitable for fractional-horsepower machines. It accepts a single-phase 200–240 VAC supply and operates with an efficiency of 95.1%, which limits heat generation during continuous duty. A continuous input current of 4.4 A reflects the current drawn from the mains, while internal switching delivers the required torque to the motor. The K1 frame measures 210 mm in height, 75 mm in width, and 168 mm in depth, providing a slim footprint for crowded panels. Typical power dissipation is 46.2 W, and the 2.5 kg mass permits DIN rail or backplate mounting without heavy support. Power and control wiring can be connected to terminals that accept conductors up to 4 mm² or 12 AWG.

On the motor side, the drive supplies a continuous output current of 3.2 A. When additional breakaway torque is required, its electronics tolerate up to 7.0 A of input current and 5.1 A of output current for short overload periods. This temporary current capacity allows the drive to accelerate high-inertia loads without tripping. The chassis has an IP20 enclosure rating, which provides protection against accidental contact with internal components when the drive is installed correctly. It is intended for installation inside a suitable cabinet because the housing is not sealed against airborne moisture. The compact chassis does not require additional forced-cooling hardware under the stated operating conditions, which helps preserve space around adjacent panel components.
