Riello NextEnergy NXE Online UPS - 250 to 800 kVA Series

The Riello NextEnergy NXE is a three-phase online double-conversion VFI SS 111 uninterruptible power supply series, available in models from 250 kVA to 800 kVA. Designed for critical infrastructure, it features an integrated IGBT three-level topology that achieves up to 97% efficiency in double conversion mode with a unity power factor. Procure.ae supplies this equipment across the UAE and MEA.

This series delivers stable sine wave output with precise voltage regulation of ±1% in battery mode, ensuring protection for sensitive loads. Efficiency reaches up to 97% while maintaining an input power factor of 0.99 and current distortion below 3%. The system supports selectable 50 or 60 Hz frequencies and operates within a 40–70 Hz input frequency range. Overload capacities vary by model, including 15x for 10ms on the NXE 250 and 11.5x on the NXE 400.

The units feature full front access and support back-to-back installation, simplifying integration into data centers or industrial facilities. An integrated colour LCD touch screen provides clear monitoring of system status. The UPS handles input voltages of 380/400/415 V three-phase with an output of 380/400/415 V three-phase plus neutral. Operating temperatures range from 0 °C to +40 °C, making it suitable for various Middle Eastern climates.
