10-200kVA

The Riello Multi Sentry system is perfect for protecting any business where problems with the energy supply could potentially compromise the continuity of all activities and services within the business. Examples of this would include companies who use large data centres and telecommunications systems to conduct their daily activities. The system has been designed and built using the most up to date UPS components and technology. Ithas a fully controlled IGBT rectifier to significantly reduce the systems impact on the grid.

The Riello Multi Sentry system is controlled by a DSP (Digital Signal Processor) microprocessor, this allows the USP system to function with maximum protection to the powered loads with no impact on the downstream systems, and optimised energy savings. The use of state-of the-art performance components and technology, allows the Riello Multi Sentry system to provide exceptional performance and efficiency, and still have impressively low running costs for a system of this magnitude.

The Riello Multi Sentry uses‘Powershield3 UPS’ software that can be used to safely shut down the system, protecting your business peripherals from data loss and Potential damage. The Multi Sentry series is available in 30-40-60-80-100-125-160-200 kVA models with three-phase input and output and on-line double conversion technology

ZERO IMPACT SOURCE

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.

BATTERY CARE SYSTEM

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. .

FLEXIBILITY

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
Two voltage level recharge meeting the IU characteristic
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 cabinet temperature sensor to assist the temperature compensating charger
Optional battery chargers to optimize recharge times
Optional dual input supplies
Optional isolation transformers for Galvanic isolation and neutral connectivity

ADVANCED COMMUNICATION

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.

LOW MANAGEMENT COSTS

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.
