Schneider Electric, DC arc flash analysis: a practical study on 800V AI data centers
Nvidia is pushing large AI training facilities toward adopting 800V DC power architectures in a drive to further densify racks. Using 800V DC for power distribution frees up valuable space in IT racks currently taken up by AC-DC power supplies, which instead can be used for additional compute. This is integral to Nvidia's roadmap toward the megawatt-scale rack (see Vendors gearing up for 800V DC adoption).
