Product Description:

The FC-280P3K7T2H2BNCXXXSXXXXAN is a variable frequency drive built by Danfoss for the VLT FC 280 Midi Drives series. The unit sits between the mains supply and a three-phase induction motor, converting fixed-frequency power into a pulse-width-modulated output. A PLC or stand-alone control loop can adjust the output frequency and amplitude to regulate motor operation. This arrangement provides control over speed, torque, and energy consumption in conveyors, centrifugal pumps, ventilation fans, and other motor-driven equipment without relying on mechanical throttles.

The drive provides a continuous output of 3.7 kW, which is the heat-limited power that the inverter can supply during continuous operation. This output corresponds to 5.0 HP for applications that use imperial units. The input section accepts a three-phase 200–240 VAC supply, allowing direct connection to compatible low-voltage industrial mains without a transformer. The model has no brake chopper, so it cannot route regenerated energy to an external braking resistor by itself. Applications that require rapid deceleration must use suitable external braking equipment or a regenerative module to manage energy returned by the motor.

The enclosure has no integrated display, so local parameter viewing and adjustment require a compatible detachable keypad. Parameters may also be accessed through supported remote control and communication tools, allowing the drive to operate without a permanently installed operator panel. The electronics use uncoated circuit boards, making the unit more appropriate for clean and controlled electrical enclosures than for locations with corrosive vapors or heavy airborne contamination. Proper cabinet ventilation helps remove heat produced by the power electronics during continuous motor operation. The installation area should also protect the internal electronics from moisture, conductive dust, and chemical exposure that could affect uncoated components.
