Description
Sentryum AC Uninterruptible Power Supply
10kVA – 40kVA Single & Three Phase Output
Sentryum is Riello UPS’s third generation of transformerless ON LINE UPS. Delivering outstanding performance and up to 96.6% efficiency in a compact footprint, it’s a proven solution for smaller and medium Data Centers and all mission-critical applications for IT, commercial and industrial systems, telecommunications, transport infrastructures and the medical area.
From now Sentryum is available also in 30 and 40 kVA models and in 2 different cabinet sizes to maximise your battery autonomy and make the most of your valuable floor space: Active (ACT), 2 battery strings in 0.35 m2 footprint or Xtend (XTD), 2 or 3 battery strings in 0.4 m2 footprint.https://www.youtube.com/embed/wiv0W1ly1bUhttps://youtu.be/S1iHY6T_h8kThe 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 0.25m2 and volume of 0.17m3
- 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 0.35m2 and volume of 0.33m3
- 380mm x 850mm x 1025mm (W x D x H)
- 1 or 2 internal battery strings
Xtend (XTD)
- Footprint less than 0.4m2 and volume of 0.5m2
- 440mm x 840mm x 1320mm (W x D x H)
- Up to 3 internal battery strings in a single cabinet
- Option to add an isolation transformer
- Can upgrade enclosure protection from IP20 or IP21 to IP31
High Efficiency
Sentryum is a true ONLINE double-conversion UPS system providing the very highest levels of power availability, flexibility and unrivalled energy efficiency with superior performance for any small data centre and mission-critical applications.
With a full power rating (kVA=kW unity pf), the Sentryum provides the maximum available power without any de-rating. Thanks to the three-level IGBT inverter topology (constructed using modules rather than discrete components) and innovative digital control, the Sentryum provides up to 96.6% overall efficiency, whilst maintaining a reduced number of components, connections and ribbon cables, which increases the overall system reliability, thanks to a higher MTBF.
Flexibility
With its flexible range of three solutions, configuration, performance, accessories and options, Sentryum is suitable for use in a wide range of applications:
- Suitable for powering capacitive loads, such as blade servers, without any reduction in active power from 0.9 lead to 0.9 lag
- ON LINE, ECO, SMART ACTIVE and STANDBY OFF operating Modes – compatible with central power supply systems (CPSS) applications
- Frequency converter mode
- Cold start to switch on the UPS even when there is no mains power present
- Parallel configuration up to 8 units for three-phase version
- Optional temperature sensor for external battery cabinets, to assist recharge voltage compensation
- High power battery chargers to optimise charge time in the event of long runtimes
- Dual input mains power supply (not applicable on Compact, optional for Active, standard on Xtend version)
- Air filter door on Xtend version to protect UPS placed in dusty environment
- Compatibility with alternative backup energy sources rather than lead batteries (NiCd or Li-ion batteries or Supercapacitors)
Advanced Communications
Sentryum is equipped with a coloured graphic touch screen display providing UPS information, measurements, operating states and alarms in different languages.
The default screen displays the UPS status, graphical indication of the energy path through the UPS and the operational condition of the various assemblies (rectifier, batteries, inverter, bypass) within the UPS.
Furthermore, the user interface includes a UPS status led bar which delivers immediate and clear information regarding the overall status of the UPS by changing the colour (light blue, dark blue, orange and red) according to the operating mode and condition.
