Product Description:
The FC-301P22KT2131F0577 is an AC variable frequency drive manufactured by Danfoss within the VLT FC 301 Automation Drives series. By modulating the voltage and frequency supplied to an induction motor, the device enables precise speed and torque control in conveyors, pumps, and general process equipment. Its compact chassis and three-phase input make it suitable for decentralized panels where reliable motor regulation is required across a 200 to 240 volt network.
This model delivers a continuous apparent power of 35.1 kVA at 230 V and maintains a motor terminal current of 88 A during heavy operation, allowing stable torque production without derating. It accepts a mains supply ranging from 200 to 240 VAC, and the inverter section can generate output frequencies from 0 to 590 Hz, so the connected motor may run well above its base speed when required by the process. At rated load, the efficiency is 0.97, which limits waste heat to 874 W and supports compact enclosure layouts. For cyclical peaks, the drive supports a 150% overload for one minute every 10 minutes, matching applications that require short bursts of additional torque. An internal control algorithm reaches rated flux in 1 ms, while starting torque can rise to 160% for 60 seconds, ensuring quick acceleration of high-inertia loads.
Power capacity is established by a continuous mechanical output of 22 kW, so the unit covers midrange fan or compressor duties without oversizing. Operation remains supported at ambient temperatures up to 55 °C, and the full rating is retained below an altitude of 1,000 m, simplifying placement in warm production facilities. The inverter synchronizes with 50 or 60 Hz supply lines within a ±5% tolerance, and its three-phase topology keeps the input current balanced at 80 A during nominal service. Output voltage ranges from 0% to 100% of the selected mains voltage, permitting controlled soft-start ramping. Regenerative braking requires appropriate external hardware to manage energy returned by the motor during deceleration.
