Liebert® Hipulse-S is carefully designed to maximize the “availability” of your critical loads to ensure that business is protected to the extent possible against power failure and J or power quality problems. This is the Prime Objective for which the Liebert® Hipulse-S is built. Beside this, Liebert® Hipulse-S is designed to address many other “customer values”.
