High density solutions

Cyberex offers the complete current limiting, selectively coordinating solution for

your high power, high efficiency data center

The industry demand to increase data center

efficiency and push the limits of power density at

the rack has introduced new design trends. While

one proposed solution, raising the distribution

voltage in the whitespace, helps meet these

demands, data center systems designed at higher

voltages (415V, 480V) provide system owners and

designers with a new set of challenges and

concerns to overcome.

Selective coordination,increased arc flash potential, protecting sensitive

IT equipment and complying with SCCR and IR

code requirements take center stage. These

heightened concerns are mainly driven by the

removal of a transformer and the potential

increase in available fault current when compared

to traditional 208V designs. With the high available

fault currents, average main and branch breaker

combinations will not allow branch breakers to trip

independently of the main, forcing the shutdown

of an entire panelboard to clear an overcurrent on a

branch circuit. This lack of coordination will in turn

cause unnecessary downtime to critical server loads.
