Product Description:

Danfoss supplies the FC-202P30KT4131Z0720 frequency converter as a member of the VLT FC 202 AQUA Drives series. This three-phase variable-frequency drive is intended for speed control of centrifugal pumps, blowers, and other water-handling equipment used in industrial automation. By modulating motor voltage and frequency, the unit allows pump flow to match real-time demand, improving energy efficiency and reducing mechanical stress on connected machinery. This operating method is particularly useful in systems where flow requirements vary throughout the day or across different production cycles.

The drive is rated for 30 kW of electrical output, equivalent to 40 HP, so it can run medium-sized induction motors commonly found in municipal or industrial pumping stations. Its input section accepts 380 - 480 VAC three-phase power and has continuous apparent power demands of 42.3 kVA at 400 V and 41.4 kVA at 460 V. Conversion efficiency reaches 0.98, which minimizes energy lost as heat during normal operation. The maximum upstream fuse rating is 80 A, providing a clear limit for circuit protection. The drive maintains consistent torque across the stated input voltage range and supports balanced loading from the three-phase supply.

The electronics operate at ambient temperatures up to 50 °C without derating and withstand a noncondensing relative humidity of 95%. Full current is available at elevations up to 1,000 m, with output progressively derated for operation at elevations as high as 3,000 m. Motor leads may extend to 150 m when shielded or 300 m when unshielded, providing flexibility for installations with remote pump rooms. Surge behavior includes a peak line-to-line voltage of 1.000 kV and a voltage rise rate of 3.100 kV/µs, with a rise time of 0.271 µs at a cable length of 15 m. These surge values must be considered when selecting motor insulation and cable arrangements for the connected equipment.
