Product Description:
The FC-301P30KT4131B6084 is a variable frequency drive manufactured by Danfoss and supplied under the VLT FC 301 Automation Drives series. It is intended to modulate power for three-phase induction motors used in material-handling systems, pumps, and ventilation equipment. After accepting plant power through its input terminals, the unit produces a pulse-width-modulated output that allows motor speed, acceleration, and braking torque to follow commands from a PLC or dedicated controller. This control method supports adjustable-speed operation across a range of industrial processes while reducing the mechanical stress associated with direct-on-line starting.
The inverter has a continuous motor output rating of 30 kW (40 HP). It connects to a three-phase supply from 380 to 480 VAC and permits a maximum mains imbalance of 3.0%. The drive can be energized only once per minute to limit inrush heating and protect the DC-link components. VVC+ scalar-vector control provides 160% starting torque for 60 seconds, while a separate variable-torque overload capacity of 110% for 0.5 seconds accommodates short surges from fans or pumps. The drive can increase motor frequency to 590 Hz, and flux optimization remains available up to 300 Hz to reduce core losses. Its IE2 efficiency classification supports energy-efficient operation with centrifugal loads and other applications that benefit from variable-speed control.
Regenerative events activate the brake chopper at 778 V DC, and a high-voltage warning appears when the DC link reaches 810 V. An overvoltage alarm is issued at 820 V DC to protect the capacitors from excessive electrical stress. The permitted ambient temperature reaches 45 °C without derating, allowing the drive to maintain full output under typical industrial cabinet conditions. Full output is also available at elevations up to 1,000 m, while operation at elevations up to 3,000 m requires a proportional current reduction. When incoming line conditions remain within the permitted range, the converter maintains a true power factor of at least 0.9, which reduces unnecessary loading on the supply network.
