Product Description:
The FC-301P11KT4134L2955 is an AC variable-frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. It converts fixed three-phase mains power into a modulated output that allows controllers to adjust induction motor speed and torque in conveyor, pump, and fan applications. Matching motor speed to real-time load demand can reduce energy consumption and mechanical stress in automated production cells. The drive also provides responsive motor control for processes that experience frequent changes in speed or load.
The input section accepts a three-phase supply of 380–480 VAC, and the inverter delivers a continuous motor output of 11 kW, equivalent to 15 HP. Its power stage can generate output frequencies up to 590 Hz, allowing precise regulation of compatible high-speed motors. Overall efficiency is rated at 0.98, which helps limit heat loss inside control cabinets. The displacement power factor exceeds 0.98, while the true power factor is at least 0.9 under the applicable operating conditions. The unit tolerates a phase imbalance of 3.0%, and only one power-up per minute is permitted to protect the DC-link components. Its electronic control can ramp torque in 1 ms when operating in flux mode or in 10 ms under VVC+ vector control, providing a quick response to changing loads.
For intermittent overloads, the output stage sustains 160% for one minute in every 10 minutes, while starting torque of 160% for 60 seconds assists with accelerating high-inertia loads. In enclosed installations, the factory-installed EMC filters support shielded motor cables up to 50 m without exceeding applicable radio-frequency emission limits. When flux control is selected, the algorithm maintains magnetizing current at frequencies up to 300 Hz, helping preserve torque at elevated motor speeds. Operation is permitted at altitudes up to 1000 m without derating and up to 3000 m with a proportional reduction in current. The drive also provides a variable-torque overload margin of 110% for 0.5 seconds, giving the motor additional short-term capacity when the connected load changes abruptly.
