Riello UPS has added a new range of transformerless online UPS systems to its portfolio. Designed for smaller data centres and mission-critical environments, the 10-20 kVA Sentryum range has fewer components, cables and connections than Riello’s best-selling Multi Sentry (MST) series for a more compact design and easier maintenance.
The UPS comes in 10, 15, and 20 kVA versions and a choice of three frame sizes to suit different space and battery runtime requirements. The range delivers full-rated unity power, with an operating efficiency of 96.5% in double conversion online mode, even at loads of 50-75%. Up to eight Sentryum units can be used in parallel to scale up capacity or provide redundancy.
