Riello UPS NextEnergy NXE Online UPS Series

The Riello NextEnergy NXE is a three-phase online uninterruptible power supply series covering capacities from 250 to 800 kVA. Utilizing transformer-free double conversion technology, it delivers stable sinusoidal output with up to 97% efficiency. Procure.ae supplies this equipment across the UAE and wider Middle East & Africa region.

This online UPS series features an integrated IGBT three-level design operating in VFI SS 111 mode. It achieves unity power factor where kW equals kVA, with input distortion below 3%. Efficiency reaches up to 97% during double conversion. The system supports selectable frequencies of 50 or 60 Hz and maintains output voltage stability within ±1% under static conditions.

The units handle input voltages of 380/400/415 V three-phase with a frequency range of 40-70 Hz. Output remains a clean sine wave with less than 3% distortion on non-linear loads. Forced air cooling manages heat within an operating temperature of 0 °C to +40 °C. Back-feed protection is included, and the series fits IP20 enclosures for industrial or commercial use.
