Tripp Lite Line Conditioners keep equipment working through low voltage conditions (brownouts) without using an emergency power source such as a UPS system or auxiliary generator. Line Conditioners automatically adjust over- and undervoltages to provide safe, computer-grade AC power that meets ANSI C84.1 specifications. All Tripp Lite Line Conditioners are covered by up to $25,000 Ultimate Lifetime Insurance which cover connected equipment against surge damage…for life!
