System Structure - Gamatronic CENTRIC 50 kW User Manual

2. I
NTRODUCTION
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 is designed to protect 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 has a "true on-line battery" design in accordance with IEC62040-3. It is a "green" power solution
thanks to low input THD, and provides regulated, stable power to your loads. Centric employs active
current balancing between power modules, and delivers overall electrical efficiency of up to 96 %, up to
98 % in backup mode.
