The Sentryum (S3T) range is the third generation of Riello UPS On-Line without transformers.

Sentryum is an improvement on the popular Multi Sentry (MST) series and has been developed based on extensive customer feedback. Available in 10-15-20 kVA versions.

S3T redefines the concept of flexible power protection by offering three different cabinet solutions to meet the different needs of small data centers and "mission critical" applications:

Compact (CPT)

  • Footprint less than 0.25 m2 and volume <0.17 m3

  • 280mm x 840mm x 700mm (L x W x H)

  • 1 internal battery branch

  • Designed especially for extremely tight spaces

Active (ACT)

  • Footprint less than 0.35 m2 and volume <0.33 m3

  • 380mm x 850mm x 1025mm (W x D x H)

  • 1 or 2 internal battery branches

Xtend (XTD)

  • Footprint less than 0.4 m2 and volume <0.5 m3

  • 440mm x 840mm x 1320mm (W x D x H)

  • Up to 3 internal battery branches in a single cabinet

  • Possibility of adding an isolation transformer

  • IP20 or IP21 version available with IP31

Sentryum is made with advanced components designed to perform flawlessly even at high temperatures of up to 40 ° C. For example, it includes a dual-core DSP processor and a three-level high frequency (18 kHz) inverter module.

This allows S3T to provide nominal power (kVA = kW 1 pf) with exceptional operating efficiency of up to 96.5% in ON LINE double conversion mode.

Available with three-phase / single-phase input, single-phase output or three-phase input and output, the UPS has an exclusive control system that reduces harmonic voltage distortion (<1% with a resistive load and <1.5% with a non-load. linear). It has a high overload capacity (125% for 10 minutes, 150% for 1 minute) and a high short-circuit capacity (270% for 200 ms and 150% for 300 ms), which allows it to handle peaks sudden load without intervention of the static bypass line.

Possibility of simultaneously installing up to 8 S3Ts to increase capacity or operate in redundancy (N + 1 configuration). The closed loop system ensures that UPSs continue to operate even if the communication cables are cut.

The redesigned 5-inch color touchscreen display clearly highlights UPS measurements and operating states, while an innovative LED status indicator automatically changes color (blue, dark blue, yellow, red) to depending on the operating mode and the states of the inverter.

Full range of user-controllable operating modes including:

ON LINE
ECO (efficiency up to 99%)
SMART ACTIVE
Emergency (STANDBY OFF)
Frequency converter

The Sentryum range is suitable for sealed lead acid batteries (VRLA), AGM and GEL batteries, forced ventilation and nickel cadmium batteries. It is also compatible with the most modern alternative energy sources, such as lithium-ion batteries and supercapacitors.

The extreme availability of the battery recharge current, up to 20 A for the power range of 20 kVA / kW, makes Sentryum perfectly suitable for applications requiring extended backup times.

The S3T integrates USB, RS232 and RJ10 ports, as well as various slots for inserting parallel and network communication cards. It is compatible with the full line of Riello UPS networking and management software, including PowerShield3 and PowerNetGuard.
