The Riello UPS Dialog Plus UPS range is the ideal solution for computer and telecoms hardware requiring protection from a wide range of power problems with a sinewave supply, advanced communications capabilities and long runtimes.
The Dialog Plus PowerRak UPS range is accepted for use on Network Rail infrastructure - certificate number PA05/01765 - as a telecoms UPS.
Uninterruptible Power Supply - on-line power protection
The Dialog Plus UPS series includes the 700-1000-1500-2000-3000VA models and uses double conversion on-line technology (VFI). Dialog Plus S models have internal batteries. 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.
