Product Description:
The FC-301P7K5T4134L2979 is an AC variable frequency drive manufactured by Danfoss within the VLT FC 301 Automation Drives series. The unit converts fixed-frequency, three-phase mains power into a modulated output that allows plant controllers to adjust induction motor speed and torque. Regulating the motor electronically reduces the need for mechanical throttling in pumps and fans. The drive can also control conveyor modules and other variable-speed equipment across industrial automation lines.
The drive accepts a mains supply of 380–480 V AC, matching common low-voltage distribution panels. Its rated motor output is 7.5 kW, which corresponds to 10 HP for midsize motors used in HVAC and material-handling equipment. Under nominal load, the drive draws 14.4 A from the supply and delivers 16 A through its output terminals, providing useful values for selecting cables and protective devices. Digital control inputs can withstand up to 28 V DC. Sequential power-ups are limited to two per minute to reduce inrush stress on the internal components. Shielded motor cables can extend up to 50 m, while unshielded cables can extend up to 75 m before output filters are required.
Transient demand is supported by an overload capacity of 160% for one minute every ten minutes, allowing the inverter to start high-inertia loads without immediate derating. During an overload, the input current can rise to 23 A, and the output current can reach 25.6 A. The overall conversion efficiency is 0.97, while approximately 255 W of processed energy becomes heat that panel ventilation must remove. The DC link includes staged safeguards for regenerative conditions. The brake chopper activates at 728 V DC, followed by a high-voltage warning at 810 V DC and an overvoltage alarm at 820 V DC. These thresholds allow the drive to respond progressively as regenerative energy raises the DC-link voltage.
