Fancy an upgrade? Uninterruptible power supply manufacturer Riello UPS has expanded its transformerless Sentryum series with new 30 and 40 kVA versions.
The two additions complement the 10-15-20 kVA models already available in the Sentryum range, which is the company’s third generation of transformer-free solutions.
Delivering full-rated unity power (power factor 1) and up to 96.5% online efficiency, the Sentryum is designed to meet the needs of small and medium-sized data centres, as well as similarly mission-critical applications in the IT, telecoms, transport, and medical sectors.
The two new 30-40 kVA models come with a choice of cabinet sizes to maximise battery autonomy and optimise floor space. The Active (ACT) chassis can house up to two battery strings in a footprint of just 0.35m2, while the Xtend (XTD) option needs just 0.4m2space and holds up to three battery strings.
Leo Craig, managing director of Riello UPS commented, “With its combination of flexibility, performance, and compactness, the Sentryum has quickly become one of our most popular products.
“With these two new additions, it gives data centres and other similar applications even more options with which to protect their critical equipment.”
As well as its exceptional efficiency and compactness, the Sentryum also features a unique control system that helps minimise harmonic voltage distortion, while it has outstandingly high overload and short circuit capacity too. This enables the UPS to deal with sudden peak loads without having to transfer to bypass.
Up to eight Sentryum UPSs can be paralleled together to increase capacity or redundancy. While the units also feature a large five-inch touchscreen colour display panel along with an intuitive LED status indicator that changes colour depending on the operating mode and condition of the UPS system.
The Sentryum expansion comes hot on the heels of Riello UPS also extending its super-efficient NextEnergy (NXE) range of UPS systems with a new 600 kVA version.
