Riello S3M20ACT-A0 20000VA Dual-Online UPS power supply system. The Sentryum (S3T) range is Riello UPS's third generation of transformerless online uninterruptible power supplies. Available in 10-15-20 kVA versions, the Sentryum improves on our popular Multi Sentry (MST) seriesand has been developed following extensive customer feedback. The S3Tredefines the concept of flexible power protection by offering three different cabinet sizes tomeet the varied needs of small data centres and mission-critical applications: Active (ACT)
  • Footprint less than 0. 35 m2andvolume of0. 33 m3
  • 380mmx 850mmx 1025mm(W x D x H)
  • 1 or 2internalbattery strings
The Sentryum is manufactured used state-of-the-artcomponents designed torun flawlesslyat temperatures up to 40 ∞C. These includea dual-core DSP processor and three-level inverters that operate at high frequency (18kHz). This ensures theS3T delivers full-rated power (kVA=kW 1pf)with exceptional operating efficiency of up to 96. 5% in online double conversion mode. Available asthree-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 Sentryumhas 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 togetherin parallel to scale capacity or build in redundancy (i. e. N+1 configuration). Closed loopsystem 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 crucialUPS measurements and operating statuses. While an innovative new LED status indicatorautomatically changes its colour(light blue, dark blue, yellow, red)depending on theoperating mode and condition of the UPS. The Sentryum range issuitable for use with sealed lead-acid (VRLA), AGM, GEL, open vent or nickel cadmium batteries, as well asalternative backup sources such as supercapacitors and lithium-ion batteries. It incorporates sophisticatedbattery management systems, such asdeep discharge protection and recharge voltage compensation,to ensurethe best performance and operating life. Higher-powered (20 A) battery chargersare available for longer runtime applications. TheS3T incorporates USB, RS232, and RJ10ports, plus various slots to insert parallel and network communications cards. It is compatible with the full range of Riello UPS networking and UPS management software, including PowerShield3and PowerNetGuard.
