Product Description:

The FC-301P30KT2131H4898 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. Inside an industrial control panel, it converts constant three-phase mains power into a regulated output that lets motion controllers adjust motor speed, torque, and direction without mechanical throttling. This capability makes the drive a compact component for automated conveyors, centrifugal pumps, and ventilation fans where energy use must track real-time load requirements.

The inverter can supply a continuous output current of 115 A, which is the maximum line-to-motor current available during steady operation. Electrical power delivery is rated at 30 kW, which corresponds to 40 HP. The input section accepts 200–240 VAC three-phase power, while the output stage operates at frequencies up to 590 Hz, allowing motor frequency to be matched to process speed. Flux mode is limited to 0–300 Hz for applications that need constant torque at very low shaft speeds, and the inverter can modulate output voltage between 0 and 100 percent of the supply voltage. A mains frequency tolerance of 50 or 60 Hz ±5 percent and automatic phase-loss monitoring support operation on utility grids with moderate frequency drift.

Upstream circuit sizing is based on an apparent power demand of 45.8 kVA at 230 V, while overall conversion efficiency reaches 0.97, allowing most input energy to reach the motor terminals as usable work. Power quality is maintained with a displacement factor above 0.98 and a true power factor of at least 0.9, reducing the reactive load on facility transformers. Emitted radio-frequency noise meets EMC category C2, enabling installation in commercial and light-industrial areas when shielded motor cable lengths remain within 50 m or unshielded cable lengths remain within 75 m. An integral relay rated at 240 V AC and 2 A provides dry-contact status signaling to external safety or alarm circuits.
