4 Frequently Asked Questions about “400V Communication Power Supply Rack Distributor - BlackVolt Energy Storage”

How is 400VDC generated?

PSUs. The output of the ±400VDC from the power shelves is collected and distributed via a vertical busbar spanning the full height of the rack. The source of the ±400V is generated by the power shelf or energy storage devices and is transferred via the rack busbar which also is connected to the HVDC Output Protection and Control Modules.

What is 400VDC routing in power rack & to it rack?

400Vdc routing in the power rack and to IT rack implemented as 3wires+PE as +400Vdc, Midpoint, -400Vdc, and PE. All outputs are floating voltage design, reference Figure 2 and 3 where mid-point is connected to PE through a High Resistive Midpoint Grounding Scheme. Resistor values is design dependent.

What is a Diablo 400V mechanical rack?

The base of the mechanical rack follows the Open Rack standard. Currently three companies have worked together to provide a high-level overview of the Diablo 400V architecture. The goal is to standardize items such as, high voltage connectors and mating interfaces. Transferring power at a higher voltage is more efficient, reduces I2R losses.
