Efficient power infrastructure – waste not, want not |
| Street power – power
entering the datacenter from “the street” is typically 3-phase 480V
in the United States. Each stage that it passes through, including the very
copper wire transmitting it reduces its efficiency. |
Stages within a
datacenter leading to power loss
- 3-phased 480VAC power enters the data
center and passes through a UPS that can reduce power between 2% and 10% (for
modern-day UPS’s).
- Data center PDUs rectify this power to
208V with a 7%-25% loss of power
- 208VAC current drives power supplies
with a loss of 20%-35%
- A/C signals can experience an
efficiency loss of 2-10% by just traveling though the wire
|
| By the time power reaches the
mainboards for actual computing, it can lose nearly 50% of its efficiency.
|
| Angstrom solution is a high
efficiency 480VAC 3-phase rectifier that converts VAC to 300VDC. Each blade, in
turn, requires DC power and efficiently converts it to EPS standard used by
most standard motherboards. |
Angstrom power
solution savings:
- 3-phase rectifier and DC power supply
combination average at 84% efficiency, saving 34% in efficiency.
- DC power solutions average at
approximately 93%, not including the rectification of A/C signal to DC.
