Product Description:
The FC-301PK55T2131X7291 is an AC variable frequency drive manufactured by Danfoss and positioned in the VLT FC 301 Automation Drives series. It functions as the power stage between a three-phase utility supply and a 200–240 V induction motor, converting line voltage into a pulse-width-modulated waveform with adjustable frequency. In automation cells, the unit provides speed regulation, process optimization, and soft starting for compact conveyors, dosing pumps, and ventilation fans.
The inverter is rated at 0.55 kW, which is the maximum continuous electrical power it can deliver to the motor terminals. This output corresponds to 0.75 HP for applications that use imperial units. Its overall efficiency is 0.95, meaning approximately five percent of the consumed energy is lost as heat inside the enclosure. The power stage accepts a 200–240 VAC three-phase input without requiring a transformer and maintains the correct DC-link voltage throughout that range. Continuous motor current is limited to 3.50 A, which affects conductor sizing and drive thermal loading. A 12-bit analog output sends scaled speed or torque signals to external indicators or controllers. The digital sink port handles up to 40 mA for relay or PLC interfacing.
For transient peaks, the device provides 5.60 A, and its overload capacity is 160% for 1 minute every 10 minutes to prevent nuisance trips during demanding accelerations. When supplied at 230 V, its apparent power demand is 1.39 kVA, which can be used when sizing upstream protective devices. Internally, the switching and control electronics dissipate 42 W, allowing airflow requirements to be calculated for the enclosure. A brake chopper engages at 365 V DC, permitting fast stops when an external resistor is connected. Shielded motor leads may extend up to 50 m, while unshielded leads may extend up to 75 m when the installation permits unshielded routing.
