Operating Mode (Selectable)Description
ECONOMY Mode

Allows you to select Line Interactive topology , increases operating efficiency to typically 98%.

FREQUENCY CONVERTER

System can be set for 50/60 or 60/50Hz

ON-LINE

Affords MAXIMUM protection to load (default).

SMART ACTIVE

The UPS automatically selects the operating mode based on mains power supply quality.

STANDBY-OFF

The UPS supplies the load only when the mains fails. The Inverter starts with a progressive start-up.

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 suit 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). Sentinel Dual is suitable for installation in any populated environment.

USER SELECTABLE CUSTOMISATION OPTIONS

  • Operating modes:

– 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 or 380-400-415Vac three-phaseAuto 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 OUTPUT POWER

  • Filtered, stable and reliable output voltage – On-Line double conversion (VFI) technology in accordance with EN50091-3, with EMI filters
  • Guaranteed output quality even with highly 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.

HIGHLY RELIABLE

  • Completely digitally controlled
  • Uninterrupted automatic by-pass
  • The by-pass can be activated manually
  • Use of IMS (Insulated Metallic Substrates) modules.

ADVANCED DIAGNOSTICS

  • 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
  • Extended autonomies using additional Battery Extension Packs.
  • Increased ride through (without batteries) on mains breaks up to 40ms and for input voltage 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 bypass.

Sentinel Dual is an on-line double-conversion UPS in accordance with VFI-SS-111.
