Product Description:
The FC-301P11KT4134L2920 is an AC variable-frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. Deployed in plant automation, it modulates induction motor speed so pumps, fans, and material-handling equipment match real-time load requirements instead of running at a fixed mains frequency. The unit provides a dedicated power stage for machinery used throughout general industry, where adjustable motor speed can reduce unnecessary energy consumption and improve process control.
It accepts a three-phase mains supply of 380–480 VAC and converts this input into a regulated output rated at 11 kW, equivalent to 15 hp at the shaft. The inverter can raise the output frequency to 590 Hz, while flux mode is limited to 300 Hz, allowing a choice between constant-torque and field-weakening operation. High starting requirements are supported by a torque reserve of 160% for 60 seconds and an intermittent overload capacity of 160% for one minute in every ten. Dynamic events are handled by a 1 ms torque rise under flux control and a 10 ms rise when VVC+ is selected. Full-current service is maintained at 45 °C, and overall efficiency meets the IE2 benchmark. Control inputs tolerate up to 28 V DC on the digital terminals, aligning with standard PLC output cards.
Protective logic issues a bus alarm at 820 V DC to limit stress on the DC link. The drive delivers rated performance at elevations up to 1000 m above sea level without derating, supporting installation in elevated facilities. Power lugs accept conductors up to 10 mm², providing sufficient capacity for the rated input and output current. Motor leads may be routed through shielded cable runs of up to 50 m, while unshielded runs may extend to 75 m before carrier-related losses increase. These cable limits help maintain stable motor operation and reduce the risk of excessive electrical interference in panel-mounted applications.
