Lower Total Cost of Ownership

DC power is often associated with

telecommunications where it has

delivered extremely high reliability for

decades. Since DC power is both

provided by backup power sources

and consumed by electronic

equipment, a DC power architecture

minimizes conversion stages from grid

to chip, thus enabling higher overall

efficiency with increased availability.
