The Riello UPS Sentryum S3T ACT 20 rewrites the concept of flexible power by offering a choice of three compact cabinet sizes to suit the needs of any small data centre or mission-critical application. Enhanced overload and short circuit capacity guarantee maximum availability.
Incorporating a 5-inch colour touchscreen display and an intuitive LED status indicator that automatically changes colour based on the UPS’s current operating state.
The Riello UPS Sentryum UPS (Uninterruptible Power Supply) improves on our popular Multi Sentry (MST) series and has been developed following extensive customer feedback. It is much easier and more cost-effective to maintain thanks to its fewer components and connectors.
The S3T redefines the concept of flexible power protection by offering three different cabinet sizes to meet the varied needs of small data centres and mission-critical applications:
Compact (CPT) Footprint less 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 Active (ACT)
Footprint less 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 Xtend (XTD)
Footprint less 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 Can upgrade enclosure protection from IP20 or IP21 to IP31
The Riello UPS Sentryum is manufactured used state-of-the-art components designed to run flawlessly at temperatures up to 40oC.
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 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 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 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 (Uninterruptible Power Supply).
Full range of user-controllable operating modes including: Online ECO (up to 99% efficiency) Smart Active Emergency (Standby Off) Frequency Converter
