Line-interactive UPS provides reliable battery backup and AC power protection against blackouts, brownouts, surges and line noise that can damage valuable electronics or destroy data. Backup support allows you to work through short power failures, and gives you enough time to safely save files and shut down your system in case of a prolonged blackout. Five 5-15R outlets provide both battery backup and surge protection for your computer, monitor and other crucial components. The other five 5-15R outlets are surge-protected only for printers, scanners and other non-essential equipment. ECO power-saving option turns off automatically when the device connected to the Battery Backup Master Outlet is powered down or in sleep mode. Automatic voltage regulation (AVR) corrects low-voltage conditions to protect your equipment from incremental hardware damage, data loss and performance problems caused by brownouts. Built-in audible alarm sounds to warn you of a low battery or overload conditions. More from the Manufacturer
