Riello Multi Sentry 200kVA 3/3 Phase

Please Note: This UPS will require a separate battery cabinet - please contact us for runtime details.

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.

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 2.5%

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
• 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 COST

• The MULTI SENTRY design provides exceptional performance and efficiency levels, within a very compact footprint and overall case design:
• Lowest footprint in its category - 0.37m² for the 40kVA 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 (92%) resulting in a faster payback period of three years.
