Riello UPS Dialog Plus-R

The Riello UPS Dialog Plus-R Uninterruptible Power Supply series is ideal for computer and telecoms
hardware requiring protection from a wide range of power problems and comprises the 700-1000-1500-2200-3000VA models using double conversion technology.

Dialog Plus S models have internal batteries while the Dialog Plus ER models are supplied with a larger internal charger. Both the S and ER versions can have battery extension packs but the ER is more
suitable for very long back up periods and offers improved recharge times.

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.

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 trays that connect in series to the rear panel connector on the UPS and/or a generator.
