Product Description:

The FC-280P7K5T4H2BNCXXXSXXXXAN is an AC variable frequency drive manufactured by Danfoss and supplied under the VLT FC 280 Midi Drives series. In industrial automation, the drive converts fixed-frequency mains power into a regulated output that allows controllers to adjust motor speed and startup torque without requiring contactors for routine speed changes. Typical duties include airflow regulation in packaging lines, volumetric pumping, and material-handling conveyors where electronic speed control can improve energy use and reduce mechanical wear. Its compact format is suitable for installation in control panels containing associated switching and control equipment.

The unit is rated for continuous shaft power of 7.5 kW, indicating the mechanical output available from a compatible motor under rated operating conditions. This value corresponds to 10 HP, which is commonly used in North American facilities when matching motors to existing gearboxes and driven equipment. The input section accepts a three-phase supply of 380–480 VAC, allowing connection to common industrial mains operating at 50 Hz or 60 Hz without a transformer. The lack of a brake chopper means regenerative energy produced during dynamic deceleration must be managed by the DC link or suitable external equipment. The absence of coated printed circuit boards makes a sealed or pressurized cabinet appropriate when the drive is installed in areas with high humidity or corrosive airborne contaminants.

The drive is supplied with no display, so local operation requires an optional remote keypad rather than an integrated screen. Setup and parameter access are available through a USB tool, fieldbus connection, or compatible remote interface. Both adaptation slots retain the standard adaptation configuration, supporting general variable-torque and constant-torque applications without application-specific modifications. The enclosure uses the mechanical footprint and terminal arrangement associated with the mid-power range, which supports orderly placement alongside contactors and control relays. Its thermal design is intended for use inside a ventilated panel that provides the clearances and airflow required for normal heat dissipation. The drive is designed to meet applicable CE and UL requirements when it is installed and operated according to the manufacturer’s instructions.
