Transformerless UPS for Smaller Data Centres
Riello UPS has launched Sentryum (S3T), its third generation of transformerless online UPS system designed for smaller data centres and mission-critical environments.
Available in 10, 15, and 20 kVA models, the new range puts flexibility at the forefront by offering data centre operators, IT admins, and other mission-critical applications the choice of three cabinet sizes, enabling them to maximise battery backup time to suit their needs.
The Compact (CPT) frame is designed for the most space-restricted environments, incorporating a single internal battery string in a footprint of less than 0.25m2. Active (ACT) houses up to two internal battery strings in a footprint of 0.35m2. While even though it takes up less than 0.4m2 space, the Xtend (XTD) option provides enough room to fit three battery strings inside its single cabinet.
Manufactured using state-of-the-art components including a dual-core DSP processor and three-level inverter, the new range delivers full-rated unity power and is capable of exceptional operating efficiency of 96.5 per cent in double conversion online mode, even at loads of 50-75 per cent, according to Riello UPS.
Leo Craig, the company's general manager, says:
"The new Sentryum builds on our best-selling Multi Sentry (MST) series. We’ve listened to extensive customer feedback and developed this fantastic new product, which has fewer components, cables, and connections than the MST.
