Product Description:
The FC-301P7K5T4131X7312 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series within the VLT AutomationDrive FC product group. It converts fixed-frequency three-phase mains power into a regulated output that allows system controllers to vary induction motor speed and torque. In industrial automation, the unit provides closed-loop speed control and energy optimization for pumps, fans, conveyors, and comparable process equipment. Its regulated output also allows connected machinery to respond to changing operating demands without relying on mechanical speed-control devices.
The drive accepts a three-phase supply from 380 to 480 VAC and delivers a continuous output of 7.5 kW, which corresponds to 10 HP. The inverter can generate a starting torque of 160% for 60 seconds, allowing loaded machines to accelerate smoothly. Output frequency is adjustable up to 590 Hz, while a 300 Hz flux-control ceiling helps protect motor insulation. Under nominal load, the displacement power factor exceeds 0.98, and the true power factor remains at or above 0.9, limiting reactive current. Mains phase imbalance must remain below 3.0% for stable operation. The design permits no more than two power-ups per minute to limit stress from repeated inrush current.
The drive supports installation on fixed industrial wiring under Overvoltage Category III. Its flux-control mode achieves commanded torque in 1 ms, providing a rapid response when the connected motor load changes. The standard VVC+ control algorithm settles within 10 ms for consistent speed regulation. During variable-torque operation, the drive withstands an overload of 110% for 0.5 seconds without derating. The unit meets the IE2 efficiency class, which helps limit internal heat generation during continuous operation. These operating characteristics support applications that require controlled acceleration, short response times, and efficient motor operation across a broad output-frequency range.
