Product Description:
The FC-301P37KT2131B6080 is an AC variable-frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. It controls motor speed in industrial automation by converting the plant’s three-phase mains supply into a regulated output that follows changing process demands. The drive can support conveyors, pumps, fans, and other motor-driven equipment that requires controlled acceleration, deceleration, torque, or operating speed. Its power electronics regulate the voltage and frequency supplied to the connected motor, while the control section processes external commands and operating feedback. The unit is designed for installation in a distribution cabinet with the necessary clearances, ventilation, and protective devices.
This model delivers a continuous output of 37 kW, equivalent to 50 HP, while drawing an apparent input of 57 kVA at 230 V. Its rated operating efficiency reaches 0.97, minimizing heat losses when the drive supplies a full load. The unit accepts a three-phase supply ranging from 200 to 240 VAC, and its control algorithms tolerate a mains imbalance of up to 3.0% before derating is necessary. Its Category III overvoltage classification establishes the insulation clearances required for installation inside a distribution cabinet. The logic permits one power-up per minute to help protect the DC-link capacitors from repeated charging cycles. During operation, the unit maintains a displacement power factor above 0.9, reducing unnecessary reactive current on the incoming line.
The drive’s digital control inputs accept up to 28 V DC, and each pulse must last at least 4.5 ms for reliable recognition. Overall power quality is supported by a true power factor of at least 0.9. An overvoltage trip occurs when the intermediate circuit reaches 410 V DC, protecting the bus capacitors and inverter section against excessive voltage. Control wiring may range from 0.25 mm² to 1.5 mm² when conductor sleeves are not used, providing flexibility when selecting cables for the control terminals. Shielded motor leads may extend up to 50 m, while unshielded leads may extend up to 75 m. These cable allowances permit the inverter to be mounted away from the driven equipment when cabinet placement or machine layout requires additional separation.
