4 FAQs about Which is safer for DC power supply to data center server racks

Can a data center server rack be powered by a DC power supply?

Most data center server racks are not currently powered this way, but with the advent of servers on the market that can operate with either AC or DC, it is possible to use the DC powering approach, thus eliminating extra power conversion steps and losses.

Do data centers use AC or DC power?

Data centers adopted many things from telecoms, most notably the ubiquitous 19-inch rack, which was standardized by AT&T way back in 1922. Now, those racks hold electronic systems whose guts - the chips inside the servers – fundamentally all run on DC power. But data centers distribute power by AC.

Do data centers run on DC?

Data centers adopted many things from telecoms, including the ubiquitous 19-inch rack. But even though electronics run on DC, data centers distribute power by AC “We actually still see 48V negative return DC style equipment inside Equinix legacy sites and facilities,” says Truong.

Which power is best for a data center?

As one of the biggest rock bands in the world – AC/DC – embarks on what might be their last world tour, it feels fitting to revisit that eternal question: AC or DC power, which is best for the data center? AC has been the dominant choice for decades, but DC is making steady inroads, largely because of its potential energy efficiency benefits.
