Riello UPS SENTINEL DUAL 3KVA ER SDH FLEXIBILITY OF INSTALLATION AND USE
the UPS can be installed as a floor standing tower or 19 rackmount UPS.
The front panel digital display can be pulled out (using the keys provided) and rotated to suite the installation format low noise level (<40dBA) thanks to the digitally PWM controlled ventilation system which is load and temperature dependent, and the use of an inverter with a high switching frequency (>20kHZ, above the audible range). DIALOG Dual is suitable for installation in any populated environment.
USER SELECTABLE CUSTOMISATION OPTIONS
– On-line (VFI): the inverter powers the load continuously
– Economy: the UPS mimics a Line Interactive (VI) UPS supporting the load from its battery supply when the mains fails or fluctuates wildly
– Smart Active: the UPS selects automatically whether to operate in On-line (VFI) or Line Interactive (VI) mode depending on the stability of the mains supply
– Emergency: the UPS only supports the load with its batteries when the mains fails – suitable for emergency lighting
– Frequency conversion 50 or 60Hz
Output voltage selection: 220-230-240Vac single-phase
Auto restart the mains returns from the front panel or PowerShield³ software
Automatic output delay when the UPS powers up
Automatic power down when no load is present
End of battery discharge pre-alarm.
QUALITY OF POWER SUPPLY
Filtered, stable and reliable voltage – On Line double conversion (VFI) technology in accordance with EN50091-3, a with EMI filters
Guaranteed output quality even with typical distorting IT loads with crest factors of 3:1
Low impact on the mains supply as the UPS has an input power factory near to 1, with a sinusoidal input current.
Completely digitally controlled
Uninterrupted automatic by-pass
The by-pass can be activated manually
Use of IMS (Insulated Metallic Substrates) modules.
Status, measurements, and alarms available on the standard backlit display
UPS can be updated digitally (flash upgradeable).
OPTIMAL BATTERY MANAGEMENT
Reliable battery performance (automatic and manual battery tests)
Prolonged battery life due to the unique Low Ripple Current Discharge (LRCD)
‘Hot-swap’ user replaceable batteries
Extendible back-up time using additional Battery Extension Packs or Trays
Increased ride through (without batteries) on mains breaks up to 40ms and for fluctuations ranging from 84 to 276Vac.
ENHANCED ELECTRICAL PERFORMANCE
Input protected by resettable thermally activated switch
Back-feed protection: to avoid energy being fed back into the mains should a fault occur
Increased short circuit current on the by-pass
Increased overload capacity: 150% on inverter even without a mains supply present
Performance guaranteed in temperatures up to 40°C short term
Manual switch to by-pass.
