Product Description:
The FC-301P22KT4131B3713 is an AC variable-frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. It receives three-phase mains power, reconstructs the waveform through pulse-width modulation, and supplies induction motors with adjustable voltage and frequency. This electronic speed regulation replaces mechanical throttling in conveyors, pump skids, and fan arrays, giving process controllers direct control over torque and flow while reducing reliance on mechanical speed-control components. Adjustable-frequency output also supports gradual acceleration and deceleration, reducing mechanical shock on couplings, belts, and driven equipment during routine starts and stops.
The inverter’s power module is rated at 22 kW, delivering enough continuous power for medium-duty production machinery. The incoming supply can range from 380–480 VAC, so the unit connects directly to common industrial networks. A continuous output current of 44 A matches typical full-load motor requirements, and the rectifier limits upstream demand to a maximum input of 40 A to protect feeders and breakers. Conversion efficiency reaches 0.98, limiting thermal losses to 547 W and easing cabinet ventilation. Vector-based control maintains stability up to a maximum synthesized frequency of 590 Hz, allowing high motor speeds when required by belt drives or spindle applications.
For short overloads, the drive can source 70.4 A for sixty seconds, absorbing acceleration shocks without nuisance trips. The drive is also rated at 30 HP, expressing its output in imperial units. The grid-side displacement power factor remains above 0.98, helping limit reactive current during normal operation. When unshielded cable is acceptable, the inverter supports motor leads up to 75 m. Longer cable runs may require shielded cable or output chokes to maintain suitable motor-side electrical conditions.
