Product Description:
The FC-301PK75T4131Z7249 is an AC variable frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. It converts fixed-frequency three-phase mains power into a modulated output that allows PLCs to regulate induction-motor speed and torque on pumps, fans, and conveyors. By inserting the drive into a control loop, machine builders can achieve tighter process accuracy and lower energy demand.
The input stage accepts a three-phase supply of 380–480 VAC, drawing up to 2.2 A at 380–440 V or 1.9 A at 441–500 V. At 400 V, its apparent power reaches 1.7 kVA, and its conversion efficiency is 0.96, placing the drive in energy-efficiency class IE2. Under these conditions, the inverter supplies a continuous motor current of 2.4 A and can operate without derating at altitudes up to 1000 m. Full output is maintained at ambient temperatures up to 45 °C, and the electronics limit power cycles to two per minute to protect inrush components. Output current is monitored by the control board for closed-loop regulation. Either VVC+ or Flux control algorithms can be selected to match the application’s dynamic requirements.
At a rated output of 0.75 kW (1.0 HP), the drive dissipates 46 W of heat, which must be considered when sizing enclosure ventilation. Starting sequences can deliver 160% torque for 60 s every 10 min, providing additional breakaway force for static loads. Dynamic response remains fast, with torque rising in 1 ms in Flux mode or 10 ms under VVC+ control. Output current tapers to 2.1 A on supplies above 441 V to correspond with the lower input current. The reduced current at higher supply voltages helps the inverter remain within its operating limits. Proper enclosure airflow is required to remove the generated heat during continuous operation.
