Product Description:

The FC-301P1K1T2131G4518 is an AC variable frequency drive produced by Danfoss for integration into automated machinery under the VLT FC 301 Automation Drives series. It also belongs to the wider VLT AutomationDrive FC product group and carries the internal series identifier 301. The drive delivers 1.5 HP of shaft power from a three-phase supply and is intended for adjustable-speed operation of conveyors, pumps, and fans that encounter changing loads during routine industrial production. It modulates motor frequency and voltage to match real-time load profiles while reducing unnecessary energy use.

Electrical performance centers on a continuous rated output current of 6.6 A, which is the maximum steady current the inverter can feed to the motor terminals. With a line supply between 200–240 VAC, the converter reaches its nominal power rating of 1.1 kW. At this operating point, the internal power stage has an overall efficiency of 0.96, meaning approximately four percent of the incoming energy is lost as heat. Short-term demands are handled by an overload margin of 160 % for one minute before derating begins. This overload capacity supports brief acceleration events without requiring the drive to maintain elevated current continuously. The inverter can also supply 2.63 kVA of apparent power at 230 V, while its input line draws 5.9 A during continuous operation.

Power dissipation is limited to 63 W, allowing enclosure airflow to remain moderate even when the brake chopper engages at 365 V DC. Analog feedback channels provide 12-bit resolution for process monitoring, while digital inputs tolerate up to 28 V DC. The outputs can source 40 mA to external relays, supporting low-current control interfaces in surrounding automation equipment. A high-voltage notice is issued at 405 V DC, and the overvoltage alarm trips at 410 V DC to protect the semiconductor switches and connected motors.
