Solution Brief Data Center IT Infrastructure

Scalable, in-row power delivery for gigawatt AI data centers

AI is fundamentally transforming data center architecture, introducing new power, cooling, and compute paradigms to meet unprecedented demand for advanced capabilities. With GPUs and other accelerators drawing 10X the energy of CPUs, data center infrastructure is shifting toward high-voltage DC (HVDC) power architectures able to support gigawatt-scale facilities.

Close up of a power megawatt IT rack for data centers

Inspired by the Open Compute Project (OCP), Flex 1 MW+ DC power distribution units (PDUs) support +/-400 VDC and enable the transition to 800 VDC power architectures. These in-row PDUs efficiently and reliably deliver power to high-density, megawatt-class IT racks as a power sidecar in both one-to-one and one-to-many configurations for flexible, scalable deployment worldwide.

Customization at scale

OCP-compliant to support the rapid buildout of data center capacity, Flex 1 MW+ DC PDUs significantly increase power distribution efficiency and reduce energy losses from grid to rack.

Each PDU features:

10x 110 kW power shelves with:

+/-400 Vout
Four 27 kW rectifier modules
One power shelf controller
Six 18 kW BBU or SuperCap modules

Power modules available:

+/-400 V to 50 V
7 kW
10 kW

40 AC electrical whips
(four 6 AWG Type W cables)

Rack controller and management switch

DC PDU with 12 fuse modules

HVDC busbar
