Standby power specialist Riello UPS has extended its NextEnergy (NXE) series with a new 500 kVA model.

The three-phase transformerless UPS delivers TÜV-certified efficiency up to 97% in double-conversion online mode, making it a reliable and cost-effective solution for data centre operators. 

Now available in 250-300-400-500 kVA versions, install up to eight NXE UPSs in parallel for extra power, redundancy, or autonomy. Hot System Expansion functionality enables operators to add extra units without the need to switch to bypass, while its intuitive Efficiency Control System ensures optimum performance across all load levels. 

NextEnergy provides outstanding installation versatility. Front to top ventilation and front access for maintenance eliminates rear clearance, enabling space-saving installation against the wall or even back-to-back. It also offers top or bottom cable entry and operates with or without a neutral connection. 

Its host of energy-saving features include Active ECO operating mode, which delivers enhanced 98.5% efficiency while avoiding the need for any power factor correction, and smart cooling where fan speed automatically adjusts according to the load.
