Product Description:

The FC-280P7K5T4H2BNCXXXSXXXXAX is an AC variable-frequency drive manufactured by Danfoss as part of the VLT FC 280 Midi Drives series. It converts constant-frequency three-phase input power into a variable-frequency output for controlling the speed and torque of compatible induction motors. This control supports applications such as pumps, conveyors, material-handling equipment, and other general-purpose industrial machinery. The slim enclosure fits standard control cabinets without requiring excessive panel depth, making the drive suitable for installations where available mounting space is limited.

The inverter provides a continuous output of 7.5 kW, which is equivalent to approximately 10 HP and supports medium-sized process motors. It accepts a three-phase 380–480 VAC supply, allowing direct connection to commonly used industrial power systems within that voltage range. The power stage varies its output frequency and voltage in response to control commands, enabling regulated acceleration, deceleration, and operating speed. Precise output control can reduce mechanical stress during startup compared with direct connection to line power. It also allows the connected motor to follow changing process demands instead of operating continuously at a fixed speed.

The drive is configured with the lack of a brake chopper, so applications that produce regenerative energy must use an appropriate external method for managing that energy. Its uncoated circuit boards are intended for clean, dry electrical rooms where moisture and airborne contaminants remain controlled. The front panel has no integrated display, so parameter access requires an external keypad or a supported remote communication interface. The unit uses the base configuration for both adaptation slots, with no specialized adaptation cards installed in either position. Control cabinets must provide suitable ventilation around the enclosure so operating heat can move away from the drive. The narrow housing helps preserve space for wiring ducts, protective devices, and neighboring automation components, while remote interfaces provide access to operating commands, status information, and adjustable parameters.
