ویژگی های اصلی یو پی اس Riello مدل Multi Sentry به صورت زیر می باشد:
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 optimizes 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 STANDBY 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 multi-platform communication, for all operating systems and network environments: PowerShield³ monitoring and shutdown software included with SNMP agent -
Compatible with Riello Connect (remote monitoring 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 synchronization 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
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
