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 available in 3300VA only (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.
