Tripp Lite's OMNI Line offers complete UPS protection with built‑in line‑interactive voltage regulation, intelligent monitoring and unattended shutdown capability. Built‑in isolation transformer with Faraday shield offers full isolation and complete common mode noise rejection. 1000VA power‑handling capacity supports point‑of‑sale applications, computers, internetworking equipment and home theater systems during commercial power failures. Line‑interactive voltage regulation corrects brownouts as low as 81V and overvoltages as high as 143V back to normal 120V levels, reserving battery power for use during complete power failures. Built‑in USB communications port works with PowerAlert Software and cabling to provide automatic unattended shutdown of connected network and PC applications.
