Product Description:
The FC-301P45KT4131B9054 variable-frequency drive is built by Danfoss and belongs to the VLT FC 301 Automation Drives series. As an AC inverter, it converts fixed mains input into a modulated output that allows industrial controllers to regulate induction motor speed, torque, and energy use across production equipment. Its 301 series form factor suits control cabinets that require compact power conversion and adjustable motor speed for conveyors, pumps, and similar automated machinery. The drive can serve centralized motor-control panels as well as equipment with dedicated speed-regulated axes.
This drive supplies a continuous output of 45 kW, equivalent to 60 hp, allowing it to operate midsize industrial motors. It accepts line feeds from 380 to 480 VAC using three-phase power, which aligns with typical plant distribution systems and can eliminate the need for an isolation transformer. Its efficiency class is IE2, indicating moderate electrical losses under nominal load. One analog channel handles reference signals, while two digital transistor outputs report status information and can source up to 40 mA for relays or optocouplers. A separate analog output can transmit speed feedback to remote indicators or control equipment. The drive can operate at ambient temperatures up to 45 °C without derating, and onboard monitoring helps protect the unit during operation.
Dynamic control is supported by a maximum carrier frequency of 32 kHz and an output frequency range reaching 590 Hz. This extended range allows the drive to operate high-speed spindle or blower motors above standard grid frequency. The internal analog stage provides 12-bit resolution, supporting smooth torque control at low speeds and precise interpretation of reference signals. For cable routing, the drive supports a shielded motor cable up to 50 m long; within that distance, the dU/dt slope remains below the 2.957 kV/µs limit. Field-oriented control supports a maximum flux frequency of 300 Hz. The pulse command bandwidth reaches 110 kHz, allowing the input stage to process rapid command pulses from compatible automation controllers.
