Product Description:

The FC-301P30KT2131F0578 is a variable frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. The unit converts fixed mains power into a variable-frequency, variable-voltage output so that three-phase induction motors can be accelerated, decelerated, or held at a set speed without mechanical throttling. In automated machines, this functionality allows conveyor belts, pumps, and material-handling axes to match process demand while lowering energy use and component wear.

On the line side, the drive accepts three-phase power at 200–240 VAC and tolerates supply variations of ±5% on a standard 50/60 Hz network. Its continuous output capability is 30 kW, delivered as 115 A of current over an adjustable frequency range of 0–590 Hz. Within this range, the controller modulates voltage in direct proportion to frequency, maintaining torque across the motor’s speed curve. Electrical conversion remains efficient, with an efficiency value of 0.97 that limits heat generation. A displacement power factor above 0.98 and a true power factor of at least 0.9 help reduce feeder loading. The 301 identifier aligns the model with the shared parameter structure used throughout the series.

Demand-based peaks are handled without external oversizing. The inverter is rated for 45.8 kVA of apparent power at 230 V and can provide the equivalent of 40 HP when continuous motor torque is required. Normal operation draws a maximum of 104 A from the mains. The overload class of 150% for 1 minute every 10 minutes permits transient input current of 156 A and a corresponding output current of 173 A. Output voltage ranges from 0% to 100% of the incoming bus voltage, enabling controlled motor braking and full-speed operation. Cabinet ventilation must remove 1,143 W of power loss to keep the semiconductor junctions within their permitted thermal limits.
