In general, an Uninterruptible Power Supply (UPS) provides backup power for use when the utility ac
electric power mains fail or drop to an unacceptable voltage level.
Centric
does this and much more.
Centric
protects your data and equipment and minimize downtime and other adverse effects normally
incurred by power irregularities and failures.
Voltage surges, spikes and sags are inherent in commercial utility power. Over time, these irregularities
shorten the life of equipment and components.
Centric
continually eliminates power irregularities, thus
helping to extend the life of your equipment, even through normal use when the input power is constant
and continuous.
Centric
requires very little attention or intervention during normal operation; however, you should read and
understand the procedures described in this manual to ensure trouble-free operation.
Centric employs active current balancing between its power modules, and delivers overall electrical
efficiency of up to 96 %, up to 98 % in backup mode.
