Sentinel Dual2 is the new range of high density double conversion ON LINE UPS, suitable for powering a wide range of devices such as servers, storage systems, VOIP telephony equipment, network and medical system as well as industrial applications. It is also ideal for powering and protecting Server systems with high input power factor. With only 2U rack unit height, Sentinel Dual2 is ideal for 19” rack cabinet installations.

Sentinel Dual2 has a practical, modern design and includes several performance advantages over traditional ON LINE UPS. All developed by the Riello UPS research and development team

The newly-designed inverter is one of the best energy conversion systems on the market, with a power factor 1 and high efficiency in ON LINE Mode. For business continuity applications requiring long battery runtimes, battery autonomy can be extended up to several hours using ER models fitted with more powerful battery chargers.

The front display panel includes a LCD display that shows the input and output voltages and battery readings, while the UPS operating status information can be seen immediately using the LED status bar below the display.

Sentinel Dual2 can be used in a tower or rack format, by simply turning the display and adding the supplied handles or optional runners.
Configuration is now simplified by the possibility to use the bluetooth mobile app to configure the UPS.

Konfigurácia UPS je teraz zjednodušená vďaka možnosti použiť mobilnú aplikáciu cez rozhranie Bluetooth.

DESIGNED FOR EASE OF USE

  • Rack or Tower installation by simply turning the display and adding the supplied handles or optional runners.
  • LCD screen.
  • LED status bar indicating the UPS operating mode.
  • Remote UPS shutdown.
  • Configurable via UPStoolsBT app.
  • Available in different power ratings, from 1 kW to 3 kW.
  • Available with various options, such as extended runtime with increased battery charging current.
  • Dedicated matching battery cabinets with various capacity available.

EMERGENCY FUNCTION

This configuration ensures the operation of emergency systems that must be supplied in the event of a mains power failure, such as emergency lighting, fire detection/extinguishing systems and alarms.

When the mains power supply fails, the inverter begins powering the loads with a progressive start up (Soft Start) in order to prevent overload.

Sentinel Dual2 is compliant for installation in medium-voltage transformer rooms in accordance with applicable legislation, for the power supply with reserve charge of medium-voltage coils.

HIGH QUALITY OUTPUT VOLTAGE

  • Even with non-linear loads (IT loads with a crest factor of up to 3:1).
  • High short circuit current on bypass.
  • High overload capacity: 150% by inverter (even with mains failure).
  • Filtered, stabilised and reliable voltage (double conversion on-line technology – VFI compliant with EN62040-3), with filters for the suppression of atmospheric disturbances.
  • Power factor correction: UPS input power factor 1 and sinusoidal current uptake.

HIGH BATTERY RELIABILITY

  • Automatic and manual battery test.
  • Batteries are user replaceable without switching off equipment and without interruption to the load (Hot Swap).
  • Unlimited extendible runtime using matching Battery Boxes.

LOW NOISE LEVEL

Thanks to the use of high frequency components and load-based fan speed control, the noise produced by the UPS is less than 40 dBA.

FEATURES

  • Output voltage can be selected via software (220/230/240 V).
  • Auto restart (automatic when mains supply is restored, programmable via software.
  • STANDBY ON bypass: when the machine is switched off, it automatically goes into bypass and battery charge mode.
  • Minimum load switch-off.
  • Battery discharge warning.
  • Startup delay.
  • · Total microprocessor control.
  • Automatic bypass without interruption.
  • Status, measurements and alarms available on standard backlit display.
  • UPS firmware updating via PC.
  • Input protection via resettable thermal switch (versions up to 1500 VA).
  • Backfeed protection standard: to prevent energy from being fed back to the network.
  • Configurable via UPStoolsBT bluetooth app.
  • Manual switching to bypass.
