Product Description:
The FC-301P45KT4134L2659 is an AC variable frequency drive manufactured by Danfoss within the VLT FC 301 Automation Drives series. The device converts a fixed-frequency supply into a controlled output waveform, enabling speed and torque adjustment for induction motors in automated conveyors, pumps, and fans. By integrating motor control into the unit, the drive allows mechanical output to be matched to process demand, which can lower energy use and extend equipment life. It is intended for panel installation and communicates with standard industrial control platforms through built-in terminals.
At 400 V, the drive delivers an apparent power of 62.4 kVA and supports a rated mechanical output of 45 kW. The input section accepts 380–480 VAC three-phase power and operates within a supply frequency range of 50/60 Hz ±5 %. During steady operation, the rectifier draws 82 A while the inverter supplies 90 A to the motor. Regulation is based on the VVC+ control principle, which maintains motor flux when the voltage-to-frequency ratio changes. The drive tolerates a phase imbalance of 3.0 % on an uneven power supply. At rated current, efficiency reaches 0.98, and the true power factor remains at least 0.9. A dedicated flux mode supports sensorless vector control at frequencies up to 300 Hz.
During short acceleration or braking events, the converter tolerates an input surge of 123 A and can deliver 135 A to the motor terminals. Under dynamic loading, the thermal design limits power loss to 891 W at rated load. Output modulation extends to a peak fundamental frequency of 590 Hz, supporting high-speed spindle applications when required. The available overload current provides additional motor torque during brief changes in speed or load. The controlled output waveform also allows the connected motor to operate below the incoming line frequency without mechanical throttling. Built-in control terminals provide connections for operating commands, status signals, and integration with standard industrial control systems.
