Product Description:

The FC-280P3K0T4E20H1BXC is an AC variable frequency drive produced by Danfoss within the VLT FC 280 Midi Drives series. Designed as a compact electronic controller, it modulates the voltage and frequency supplied to three-phase induction motors so automated machinery can adjust speed, ramp profiles, and torque without mechanical throttling. In industrial automation the unit fits where the larger VLT AutomationDrive is unnecessary yet simple starter solutions lack parameter depth; the Midi platform covers conveyors, pumps, and material-handling axes that need precise but economical motor regulation.

The power section accepts a supply of Three phase 380-480 VAC, aligning with typical low-voltage distribution in factories. From this input the inverter delivers a continuous shaft power of 3.0 KW, equivalent to 4.0 HP, giving enough margin for midsize centrifugal loads. The chassis carries an IP20 / Chassis rating, so it must be installed in a protective panel but allows quick access to terminals during commissioning. Conducted emissions are limited by the integrated EMC Cat C1(200V)/C2(400V) RFI filter, reducing high-frequency noise on supply cables and helping machines meet harmonic directives without external components.

For controlled deceleration the drive incorporates a Brake chopper, allowing a matched braking resistor to dissipate regenerative energy and keep the DC bus within limits during fast stops. Reliability in dusty or humid enclosures is improved by a Coated PCB, which shields traces from condensation and airborne contaminants. Parameter access is intended through remote tools because the front cover ships with No display, reducing enclosure depth and discouraging unauthorized adjustments. The internal firmware, grouped under index 280, shares macros and sequence logic across the Midi Drive FC product group, simplifying replacement or scaling to higher ratings without altering application code.
