Riello Sentinel Dual 3300VA - with 5 minutes autonomy at full load - Requires 16Amp supply.

An Uninterruptible Power Supply (UPS) for the power protection of medium sized file servers, voice and data networks, communications cabinets and telephone switches.

The Riello UPS Sentinel Dual HP UPS range is the ideal solution for computer and telecoms users wanting a flexible multiple operating format power system capable of either floor standing or 19" rackmount format for use in communication cabinets. In 2004 the product won the Electrical Products Award for innovation.

Uninterruptible Power Supply with multiple operating modes

The Sentinel Dual HP UPS is only available as 3300VA (single/single phase models) and uses double conversion on-line technology (VFI) with several other operating mode options.

In on-line mode the load is powered continuously by the inverter to remove sags, surges and brownouts, through EMI filters to suppress transients, spikes and electrical noise. Even on bypass the load is routed through the filters so that the load is not connected to raw mains.

When the mains fails, the inverter which is constantly powering the load simply draws power from the internal battery to provide complete protection.

Extended Runtimes

As the inverter is rated for continuous operation this type of uninterruptible power supply can be used to support large loads for long runtimes up to and over 7 hours or more in duration. This can be achieved using battery extension packs that connect in series to the rear panel connector on the UPS. When battery extension packs are used these may have their own mains powered chargers to maintain a reasonable recharge time of the complete battery set. For larger loads consider the Sentinel Power

Whatever the runtime installed there should be sufficient time for the protected computer systems to be shutdown in an orderly manner using the PowerShield software, supplied as standard. Additional remote monitoring can be achieved using PowerNetGuard on Wide Area Networks or the TeleNetGuard remote service monitoring system with text alerts for site problems, and the wide range of NetMan SNMP interfaces and MultiCom adapters available.
