Tripp Lite AVR Series Ultra-Compact Line-Interactive UPS, 8 Outlets, 550 VA, 420 J (AVR550U)

Protect home and office computer systems and electronics with this Line-Interactive UPS System. Some outlets have both battery backup and surge/noise protection, and some have surge/noise protection without battery backup. The "surge-only" outlets allow you to connect additional equipment without overloading the UPS or reducing the backup runtime available during an outage. Select outlets have extra-wide spacing to accommodate bulky AC adapters without blocking adjacent outlets. All Tripp Lite UPS systems also include built-in surge protection and noise filtering to shield your equipment from destructive transient voltages and electromagnetic (EMI/RFI) line noise. Use the HID-compliant USB port and your computer's built-in power management features or the USB port with Tripp Lite's free PowerAlert software to manage this UPS. Protection Type: DSL; Fax; Modem; Phone; Power; System VA: 550 VA; Backup Time at Half Load: 9 min @ 150 W; Lines: 1.
