Sentinel Dual (Low Power) (1000 – 3000 VA)

Sentinel Dual (Low Power) (1000 – 3000 VA)

On Line UPS

Sentinel Dual is the new range of high density double conversion online UPS, suitable for powering a wide range of devices such as servers, storage systems, telephony – VoIP equipment, network and medical systems as well as industrial applications.
It is also ideal for powering and protecting Blade Server systems with high input power factor. At only 2U, Sentinel Dual is ideal for 19″ rack cabinet installations.
Sentinel Dual 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 0.9 output power factor and 92% operating 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.
With energy savings in mind, Sentinel Dual is also fitted with a shut-off button to reduce energy consumption to zero during prolonged periods of inactivity.

Features

Technical Specifications

Product Brochure

Main features:

Simplified installation

  • Low noise
  • Operation guaranteed up to 40°C (the components are designed for high temperatures and are thus subject to less stress at normal temperatures)
  • On Sentinel Dual models, the output sockets can be programmed to disconnect less critical loads during blackouts (EnergyShare function).

Installation versatility
Sentinel Dual can be used in a tower or rack format, by simply turning the display and adding the supplied handles or optional runners.

Reduced running costs
The UPS is highly flexible and easy to configure. Programmable functions can be set via software or manually via the front display panel. Sentinel Dual can be configured in the following operating modes:

  • On Line, maximum load protection and output voltage waveform quality
  • ECO Mode, to increase efficiency (up to to 98%); allows you to select Line Interactive technology
  • Smart Active, the UPS automatically decides the operating mode based on the mains power quality
  • Emergency, the UPS can be selected to function only when the mains power supply fails (emergency only mode)
  • Frequency converter operation (50 or 60 Hz).

Advanced Communications
Sentinel Dual offers maximum flexibility for integration with all types of communication systems.

  • Multi-platform communication for all operating systems and network environments: PowerShield3 supervision and shutdown software for Windows operating systems 8, 7, Hyper-V, 2012, 2008, and previous versions, Mac OS X, Linux, VMWare ESXi, Citrix XenServer and other Unix operating systems.
  • RS232 serial port and opto-isolated contacts
  • USB port
  • Slot for communications boards such as Modbus/Jbus, TCP/IP-SNMP and relay contacts.

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 (On-line double conversion technology (VFI compliant with EN62040-2 class C2) with filters for the suppression of atmospheric disturbances
  • Power factor correction: UPS input power factor close to 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.

Other features

  • Output voltage can be selected via software (220-230-240 V)
  • Auto-restart when mains power is restored (programmable via software)
  • Stand-by on bypass: when the machine is switched off, it automatically goes into bypass and battery charge mode
  • Minimum load switch-off
  • Status, measurements and alarms available on standard backlit display
  • UPS firmware updating via PC
  • Manual switching to bypass.
