Datacentres for better security

Award-winning manufacturer of uninterruptible power supplies and standby power systems Riello UPS launches its third generation of transformerless UPS.

Designed for small data centres and similar mission-critical IT environments, the Sentryum incorporates 10, 15, and 20 kVA versions.

It comes with a choice of three frame sizes that enable customers to maximise their battery runtime.

The Compact (CPT) cabinet holds a single battery string. With a footprint of less than 0.25m2 is an ideal solution for the most space-restricted installations. The mid-size Active (ACT) enclosure has a footprint of 0.35m2 and can house two battery strings. Finally, the Xtend (XTD) option has enough room to fit three battery strings even though it only takes up a compact 0.4m2 space.

Delivering full-rated unity power thanks to advanced components such as a three-level inverter and dual-core DSP processor, the Sentryum offers outstanding efficiency of up to 96.5%, even at loads of 50-75%.

Riello UPS General Manager Leo Craig comments: “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. Not only does this mean it requires less space, but it also makes the Sentryum far easier and more cost-effective to maintain.”

The UPS’s high overload and short circuit capacity ensure it can handle unexpected peak loads without the need to transfer to bypass. It also features a unique control system that minimises harmonic voltage distortion.

Up to eight scalable Sentryum UPS can be paralleled together to boost capacity or ensure redundancy (i.e. N+1). And because the range runs on a closed-loop system, it won’t go offline even if there’s a problem with the connection cables.

Another innovative feature is the revamped large touchscreen colour display panel. While a new LED status indicator changes colour depending on the UPS’s current operating state.

The new Sentryum is available for pre-order from Riello UPS for delivery in Q4.
