Transformer-free three-phase UPS with IGBT three-level design delivering up to 97% ON LINE efficiency, unity power factor (kW=kVA), ACTIVE ECO Mode with active filter, peak shaving, and full front access for data centers, commercial and industrial applications.
The Riello Next Energy NXE is a high-power three-phase UPS ranging from 250 to 800 kVA, engineered for large data centers, critical industrial plants, and utility substations. It delivers the top-tier efficiency, low harmonic footprint, and flexible configurations demanded by today’s mission-critical sites.
Next Energy NXE supports parallel operation up to multi-megawatt capacities, making it equally suitable for large colocation facilities and hyperscale campuses.
Up to 800 kVA in a single cabinet keeps the UPS room compact and simplifies the electrical one-line even at very large facility power levels.
Very high efficiency in online and eco modes reduces energy bills and cooling loads substantially over the UPS operating life.
Supports parallel configurations to multi-megawatt capacity, matching the scale of modern hyperscale and colocation facilities.
Unity input power factor and low harmonic distortion reduce oversizing of upstream transformers and generators, saving capital cost.
