Riello UPS NextEnergy NXE Online UPS (250 - 800 kVA)

The Riello UPS NextEnergy NXE series comprises three-phase Online UPS units rated from 250 kVA to 800 kVA. Featuring transformer-free double conversion VFI SS 111 technology, these systems deliver up to 97% efficiency in double conversion mode. Procure.ae supplies this series for businesses in the UAE and wider Middle East & Africa regions.

The NextEnergy NXE series utilizes an integrated IGBT three-level design to achieve unity power factor, where kW equals kVA. Efficiency reaches up to 97% in double conversion mode, while current distortion remains below 3%. The systems support overload capacities of 110% for 60 minutes, with specific units offering 125% for 2 minutes. Peak shaving and Active Filter Mode (ACTIVE ECO) further optimize energy use.

These UPS units accept input voltages of 380/400/415 V three-phase with a power factor of 0.99. Output is available in 380/400/415 V three-phase + N, delivering sine wave output with less than 1% voltage distortion for linear loads. The design allows for full front access and back-to-back installation. Operating temperatures range from 0 °C to +40 °C with forced air cooling.
