Xtreme Value Tower Series XVRT-2200 Line Interactive Uninterruptible Power Supply battery backup is an ideal device to provide power protection and power failure runtime to all your small and medium sized phone systems, VoIP handsets and computers systems. Its multi-form factor (tower/rack or wall mounting) ensures a good fit with the environment in which it is to be used. UPSMON, the power management software (included with purchase) safely closes files and shuts down your devices and runs on any PC connected to the UPS. The XVRT-2200 UPS provides surge, spike and automatic voltage regulation even with weak or dead batteries via the independent battery bypass. Xtremes AVR technology also boosts battery life by conditioning voltage to your equipment instead of using the battery to do so. Hot swappable, user friendly replacement batteries are available. An RJ-45 surge protected jack is also included to protect your network.
