Product Description:

The FC-301P5K5T4131F3225 is an AC variable frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. Designed for integration into industrial automation panels, the unit accepts three-phase mains power and generates a regulated output that allows controllers to vary the speed of standard induction motors. It sits between the plant mains and motor terminals, replacing mechanical throttles with electronic control to improve process accuracy, reduce wear, and lower energy use in fans, blowers, and material-handling lines.

At its core, the drive delivers a continuous motor output of 5.5 kW. To sustain that load, it draws up to 9.0 kVA of apparent power from a 380–480 VAC three-phase supply. Electrical efficiency reaches 0.97, so only a small fraction of the input power becomes heat during operation. At the lower supply voltage range, the rectifier draws a maximum current of 11.7 A. The 4 kΩ control input impedance protects low-level reference sources from excessive current draw while allowing the drive to receive analog speed or process commands.

At the motor terminals, the inverter can supply 13 A when operating from 380–440 V or 11 A when the bus voltage is between 441 and 500 V. Thermal losses are limited to 255 W, and the drive maintains its full rated current at ambient temperatures up to 45 °C without derating. Output derating begins above an installation altitude of 1,000 m, but operation remains permitted at elevations up to 3,000 m when the load is reduced proportionally. Control feedback is delivered through a 12-bit analog output, and the digital status channel supports up to 40 mA. Shielded motor cables may extend up to 50 m, while unshielded cables may extend up to 75 m. These cable allowances support installations in which the motor is positioned away from the automation panel without requiring the drive to be mounted directly beside the connected equipment.
