Riello UPS has expanded its super-efficient NextEnergy (NXE) range of uninterruptible power supplies with a new 400 kVA model.

The much-anticipated NXE 400 incorporates the latest transformerless technologies to deliver TÜV-certified operational efficiency up to 97%, while its pioneering Efficiency Control System minimises wasted energy even at partial loads. 

Already available in 250 kVA and 300 kVA versions, the more powerful NXE 400 is a similarly-proven solution for protecting mission-critical applications in a compact footprint.  

The three-phase UPS delivers unity power factor and incorporates a whole host of energy-saving features including Eco and Smart Active operating modes that enable 99% efficiency, plus speed-controlled fans that adjust depending on the load level. 

Leo Craig, Riello UPS General Manager, commented: “Delivering category-leading efficiency in a compact footprint, we’re sure this increased power version of the NextEnergy UPS will quickly become a firm favourite with our customers.  

“Its large touchscreen display makes it easy to check all vital measurements and modify operating modes or settings, putting maximum power at your fingertips.” 

Offering flexibility with bottom and top cable entry, the NextEnergy range can operate without a neutral connection so is suitable for three-wire installations. Front to top ventilation eliminates rear clearance, allowing for space-saving back-to-back installation, while complete front panel access enables easy servicing and UPS maintenance too. 

Up to eight NXE UPS can be paralleled together to increase capacity or add redundancy. For installations in more challenging environments, redundant fans and individual fan failure alarms are fitted as standard and can be coupled with an optional IP 31 protection package. 

In a further boost for the NextEnergy range, the existing 250 and 300 kVA versions have earned a place on the Energy Technology List (ETL), a government-backed directory of recommended energy efficient products. 

Any product appearing on the ETL is eligible for tax relief under the Enhanced Capital Allowance (ECAs) scheme. This means customers buying an NXE 250 or 300 could be able to write-off up to 100% of the cost of buying the new equipment against their taxable profits.  

Other Riello UPS products on the ETL after meeting strict energy efficiency thresholds include the modular Multi Power (MPW) and the 30, 40, 125, and 200 kVA versions of the smart grid-ready Multi Sentry (MST).
