Keep critical workstations, network devices and surveillance systems running through brief outages with the Eaton Tripp Lite AVR550U line-interactive UPS. This compact UPS delivers 550VA/300W of reliable battery backup and Automatic Voltage Regulation (AVR) to maintain stable 120V output during brownouts and surges, preventing unexpected reboots and protecting data for security monitoring, NVRs, routers and POS terminals. Eight NEMA 5-15R outlets give flexible connectivity—four battery-plus-surge outlets for essential equipment and four surge-only outlets for peripherals—while 316-joule surge suppression and RJ-11 phone/DSL protection guard against spikes and line noise. The included USB (HID) port supports unattended shutdown and power monitoring with the supplied software, and the ultra-compact housing mounts on a desktop or wall to save space in security closets or small offices. With quick 6ms transfer time and practical runtime (approx. 9 minutes at half load), the AVR550U balances performance and value. Backed by Eaton’s 2-year warranty, it’s ideal for protecting IT, networking and surveillance systems.
