Riello UPS Sentryum Range of Uninterruptible Power Supplies
The Riello UPS Sentryum Range is a set of 12 UPS from 10-20 kVA designed for sites that have limited power capacity or problems with harmonics. As a result, the Riello UPS Sentryum Range is compatible with both single-phase and three-phase mains power and proved up to 96.5% efficiency.

The Sentryum (S3T) range is Riello UPS’s third generation of transformer-less online uninterruptible power supplies.
Available as 10kVA UPS, a 15kVA UPS and a 20kVA 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 three cabinet sizes to meet the needs of various different customers requirements and specifications:
Riello UPS Compact (CPT) Sentryum
- Footprint smaller than 0.25 m2 and volume of 0.17 m3
- 280mm x 840mm x 700mm (W x D x H)
- 1 internal battery string
- Specifically designed for extremely restricted spaces
Riello UPS Active (ACT) Sentryum
- Footprint smaller than 0.35 m2 and volume of 0.33 m3
- 380mm x 850mm x 1025mm (W x D x H)
- 1 or 2 internal battery strings
Riello UPS Xtend (XTD) Sentryum
- Footprint smaller than 0.4 m2 and volume of 0.5 m3
- 440mm x 840mm x 1320mm (W x D x H)
- Up to 3 internal battery strings in a single cabinet
- Option to add isolation transformer
- As a result it can upgrade enclosure protection from IP20 or IP21 to IP31
The Riello UPS Sentryum's full range of user-controllable operating modes including:
- ON LINE
- ECO (up to 99% efficiency)
- SMART ACTIVE
- Emergency (Standby Off)
- Frequency Converter
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.
