Please Note: This UPS will supply 28 minutes runtime at a full load of 9kW & is configured as a 3/3 Phase UPS.

The Riello Multi Sentry is a state-of-the-art uninterruptible power supply, achieving the highest possible level of on-line double-conversion performance (VFI-SS-111) as defined within IEC EN 62040-3.

The UPS has been designed to protect critical information and telecommunications systems, networks, services and processes whose operation could be disrupted by poor power quality and/or breaks in their mains power supply.

The Multi Sentry UPS is one of the most efficient UPS available with a minimal impact on its environment and power sources.


MULTI SENTRY UPS are easy to install, especially on sites where there is limited power capacity available, a standby generator and potentially harmonic compatibility issues:

• Low input current distortion - less than 3%
• High input power factor 0.99
• Power walk-in function to achieve progressive rectifier start-up
• Delayed start-up on mains power supply return

MULTI SENTRY also performs the role of a high specification filter, protecting its power supply sources (mains or generator) from any harmonics and reactive power generated by the loads it is powering.


  • The MULTI SENTRY Battery Care System optimises battery performance, to help extend their working life and ensure that the UPS can deliver its full-rated back-up time when called upon in an emergency.
  • Battery recharge: MULTI SENTRY is designed to work with VRLA AGM and GEL lead-acid batteries including open-vented types, in addition to Ni-Cads. Specific management features include:
    • One-level recharge to meet the requirements of the most common VRLA AGM batteries
    • Two voltage level recharge meeting the IU characteristic
    • Restricted charging to reduce electrolyte consumption and extend the life of VRLA batteries
  • Temperature compensation: to avoid excessive voltage being applied to the batteries in a high ambient
  • Battery test: to detect performance degradation and predict battery failure.
  • Deep discharge protection: to prevent the batteries being discharged below a level from which they cannot be recovered (especially when discharged over long periods with very low loads).
  • Low AC ripple current: from a high-frequency battery charger, to ensure the batteries are not subjected to this damaging element commonly experienced with some other UPS and power supply designs.
  • Wide input voltage range: from a rectifier that can work down to less than 40% of its nominal supply rating (at half load), removing the need to discharge the batteries.



  • MULTI SENTRY can be used for a wide range of applications, thanks to its configuration options, flexibility, accessories and performance levels:
    • Suitable for powering capacitive loads, for example Blade servers - without any reduction in active power, from 0.9 leading to 0.9 lagging
    • Modes of operation include: On-Line, Eco, Smart-Active and Stand-By/Off
    • Frequency conversion mode
    • Power Share connections for priority-based load shedding when the mains power supply has failed
    • Cold-start facility to switch the UPS on even without a mains power supply present
    • Extensive back-up time options using battery extension cabinets
    • Optional battery chargers to optimize recharge times
    • Optional dual input supplies
    • Optional isolation transformers for Galvanic isolation and neutral connectivity



  • MULTI SENTRY has a large front panel graphic display providing information including: real-time measurements, operating status and alarms conditions - in eight different languages
  • Advanced multiplatform communication, for all operating systems and network environments: PowerShield³ monitoring and shutdown software included with SNMP agent
  • Compatible with TeleNetGuard for the remote assistance service
  • RS232 or USB serial port
  • Three communication slots for accessories including: network adapters and volt-free contacts
  • REPO (Remote Emergency Power Off) to shut down the UPS remotely in an emergency
  • Input for connection of an auxiliary contact for an external manual bypass
  • Input for synchronisation with an external power source
  • Graphic mimic panel display for remote connection.



  • The MULTI SENTRY design provides exceptional performance and efficiency levels, within a very compact footprint and overall case design:
    • Lowest footprint in its category - 0.26m² for the 20kVA MULTI SENTRY with internal batteries.
    • High efficiency up to 96% - saving up to 35% in dissipated energy in one year compared to a more traditional UPS (91%) resulting in a faster payback period of four years.
    • High output power factor which at 0,9pF (1pF for models 160-200 kVA) provides up to 15% ( 20% for models 160-200 kVA) more active power compared to a more traditionally sized UPS - providing greater system expansion margin for further load increases.
    • Optional battery cabinet temperature sensor to assist the temperature compensating charger
