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.
