Out with the old and in with the new

Published by Lee Kelly on 28 October 2019

We are soon saying goodbye to the Multi Sentry 10, 15 and 20kVA units and hello to the new top of the line Sentryum range. Available in the 10kVA, 15kVA and 20kVA and 3 different footprints.

It’s the ideal choice for any small data centre or similarly mission-critical environment.

The new range builds on Riello UPS’s best-selling Multi Sentry (MST) series. Following extensive feedback from customers, the new units have an optimised card layout compared to the MST which cuts the number of components, cables, and connections.

This reduces the required space and makes it far easier and more cost-effective to maintain.

The Sentryum delivers “best in class” quality in terms of maximum space-saving, better battery charging capabilities, and longer backup time in a single cabinet.

Sentryum Highlights

  • Power availability: delivers full-rated power (kVA = kW 1 pf)
  • Efficiency: capable of 96.5% efficiency in online mode even at loads of just 50-75%
  • Versatility: choice of three-phase/single phase input, single-phase output or three-phase input and output
  • Scalability: run up to 8 S3Ts in parallel for increased capacity or redundancy (N+1)
  • Reliability: unique control system reduces harmonic voltage distortion; high overload and short circuit capacity enable it to handle sudden peak loads without transferring to bypass
  • Usability: large touchscreen display panel plus intuitive LED status indicator that changes colour depending on the UPS condition
  • Functionality: choice of operating modes (Online, ECO, Smart Active, Standby Off, Frequency Converter)
