Product Description:

The FC-301P18KT2134L2675 is a variable frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. Designed for three-phase induction motors in automated machinery, it converts 200–240 VAC mains power into a controllable output that aligns motor speed with process demand. The unit provides open-loop or sensorless vector control to support energy-efficient motion tasks in conveyors, pumps, and material-handling stations.

At a 230 V supply, the drive presents an apparent power requirement of 29.8 kVA and draws a continuous input current of 68 A from the line. Internally, it is rated to deliver a continuous motor output current of 74.8 A, corresponding to an output power of 18.5 kW. Conversion losses are limited, resulting in a full-load efficiency of 0.96. The vector control core tracks torque demand quickly; flux mode has a rise time of 1 ms, while the VVC+ algorithm responds within 10 ms. Frequency synthesis spans from zero to the 300 Hz flux limit, allowing compatible motors to operate across a broad speed range without magnetic saturation. The three-phase input is rectified for the drive’s DC link without requiring an external transformer.

For intermittent demands, the inverter can supply an overload motor current of 112 A for short durations, and its internal thermal design limits total heat dissipation to 740 W. The output stage supports applications up to 25 HP and reaches switching frequencies that permit a maximum synthesized speed command of 590 Hz. Control terminals provide a 24 V auxiliary rail that can source 200 mA for sensors. They also accept digital inputs up to 28 V DC and operate a relay contact rated at 240 V AC and 2 A for external interlocks. These connections allow the drive to exchange control signals with sensors, switches, and other automation components in a machine system.
