Product Description:
The FC-301PK55T4131B8982 is a three-phase AC variable frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. Positioned within the VLT AutomationDrive FC product group, it converts fixed mains power into variable-voltage, variable-frequency output so production lines can adjust motor speed electronically rather than through mechanical dampers or gear changes. This capability allows automated equipment to maintain precise process control while reducing the energy drawn from the plant supply. The drive is suitable for controlling motors in conveyors, pumps, fans, packaging machinery, and other automated systems that require adjustable speed or torque.
With an input range of 380–480 VAC, the drive draws a peak line current of 1.6 A, which must be considered when selecting upstream protection devices. Apparent power remains 1.3 kVA on both 400 V and 460 V networks, simplifying panel design for installations that use either supply voltage. The inverter provides a rated motor output of 0.55 kW, with motor currents of 1.8 A on 380–440 V grids and 1.6 A on 441–500 V grids. Operating efficiency reaches 0.95, limiting the portion of incoming energy that is converted into heat. For transient loads, the control stage supports an overload capacity of 160% for one minute in every ten minutes, allowing machinery to accelerate heavy loads without an immediate shutdown. Auxiliary terminals provide 10.5 V ±0.5 V at 15 mA and 24 V (+1/−3 V) at 200 mA, allowing connected feedback potentiometers or sensors to operate without separate power supplies.
The output section can be programmed for frequencies up to 590 Hz, while flux-optimizing control supports frequencies up to 300 Hz. These frequency limits accommodate applications ranging from slow-moving conveyors to high-speed spindles. Internal power losses are limited to 42 W, so normal enclosure airflow can help keep the heat sink within its operating temperature range. The three-phase power topology balances phase currents across the connected motor. Integrated control functions regulate output voltage and frequency in response to process commands, allowing the motor to maintain the requested operating speed as load conditions change.
