Riello UPS Sentryum | Rewriting the concept of flexible power

Sentryum is our third generation transformerless ONLINE UPS designed to maximise availability, efficiency and performance in small data centres and similar critical applications. Delivers 96.6% efficiency and unity power (pf 1).

Enhanced Performance

Sentryum builds on previous transformerless series such as Multi Sentry (MST) with an optimised card layout that reduces the number of components, cables, and interconnections. This means your UPS needs less space and is far more cost-effective to maintain.

Riello UPS Sentryum Range

Available from 10kVA UPS, up tp 120kVA UPS, the Riello UPS Sentryum improves on the popular Riello UPS Multi Sentry (MST) series and was designed using extensive customer feedback.

Consequently the Riello UPS Sentryum redefines the concept of flexible power protection by offering four cabinet sizes to meet the needs of various different customers requirements and specifications: -

Using the Sentryum Range with Batteries

The Riello UPS Sentryum (S3T) range is suitable for use with sealed lead-acid (VRLA), AGM, GEL, open vent or nickel cadmium batteries, as well as alternative backup sources such as supercapacitors and lithium-ion batteries. 

It also incorporates sophisticated battery management systems, such as deep discharge protection and recharge voltage compensation, to ensure the best performance and operating life. Higher-powered (20 A) battery chargers are available for longer runtime applications.  

The S3T incorporates USB, RS232, and RJ10 ports, plus various slots to insert parallel and network communications cards. Consequently it is compatible with the full range of Riello UPS networking and UPS (Uninterruptible Power Supply) management software, including PowerShield3 and PowerNetGuard.  

 

6 Key points about the Range

The Riello UPS Sentryum (S3T) is manufactured using the latest state-of-the-art components, and consequently it is designed to run flawlessly at temperatures up to 40 °C. These include a dual-core DSP processor and three-level inverters that operate at high frequency (18 kHz). 

This ensures the S3T delivers full-rated power (kVA = kW 1 pf) with an exceptional operating efficiency of up to 96.5% in online double conversion mode.  

Available as three-phase/single phase input, single-phase output or three-phase input and output, the UPS (Uninterruptible Power Supply) has a unique control system that reduces harmonic voltage distortion (< 1% at resistive load and < 1.5% at non-linear load). 

In addition, the Riello UPS Sentryum has high overload (125% for 10 minutes, 150% for 1 minute) and short circuit (270% for 200ms and 150% for 300ms) capacity, which enables it to handle sudden peak loads without needing to transfer to bypass. 

Install up to 8 S3Ts together in parallel to scale capacity or build in redundancy (i.e. N+1 configuration). Closed loop system ensures the UPSs continue to function even if there’s a disruption to the connecting cables.  

A revamped 5-inch colour touchscreen display panel clearly highlights crucial UPS (Uninterruptible Power Supply) measurements and operating statuses. While an innovative new LED status indicator automatically changes its colour (light blue, dark blue, yellow, red) depending on the operating mode and condition of the UPS system.
