1000VA - 3000VA Sentinel Dual Low Power - SDH Series

Sentinel Dual is the high density version of the Sentinel Pro range of double-conversion on-line UPS. Sentinel Dual is designed to power critical loads such as servers, storage systems, telephone equipment, medical systems and industrial applications; and is ideal for Blade servers with an input power factor close to unity (1).
Designed with the environment and efficiency in mind, the Sentinel Dual is part of the Riello ECO Line of Uninterruptible Power Supplies (UPS), and achieves an on-line operating efficiency of 92%
The flexible and functional design of the Sentinel Dual allows the UPS to be used as a tower unit, or by simply rotating the mimic panel, it can be used within a rackmount cabinet, taking up only 2U in height.
Available models include 1000VA, 1500VA, 2200VA and 3000VA, and incorporates a 'Power-Off' function found in other Riello ECO Line UPS.

Extended Runtimes

For applications requiring longer runtimes, Sentinel Dual can be installed with battery extension packs (ER models) which also include additional battery boost chargers.

Advanced Communication

In terms of communication, each Sentinel Dual has a built-in mimic panel with an LCD to show input and output voltages, and battery charge status. This panel can be turned through 90o to best suit the installation. The Sentinel Dual also offers maximum flexibility for integration for integration with any communication system.
Multiplatform communication for all operating systems and network environments;
Powershield3 UPS monitoring and control software included for Windows 7, 2008, Vista, 2003, XP, Linux, Mac OS X, Sun Solaris and VMware ESX operating systems and other Unix operating systems.
