The 415V Data Center
» MV – LV Transformation at UPS
PDU A
1250KVA
 5KV / 415V transformer feeds UPS
 415V in/out of UPS
 Single phase 230V distributed
server racks
» Benefits
 Transform close to load still allows
benefits of small MV cabling
 Eliminate PDU transformer cost
and efficiency losses
 Reduce footprint of many PDUs

Major Savings in MV / 415V Distribution
4MW UPS project, expandable to 8 MW
» Capex
 Reduced wiring cost by $250,000 dollars (14% of total installation) by
providing MV as close to the load (point of transformation) as possible
 Eliminate 480:208V transformers in PDUs
 Reduced MV breakers by $360,000 (11% of total hardware)
 Reduced UPS / PDU space consumption by 50%
» Opex
 Improve efficiency by 2-3% by eliminating transformation steps ($65,000
annual savings @ 3MW; $171,000 annual savings @ 8MW)
 Improve power supply (server) efficiency by 1.5-2% operating at higher
voltage ($42,000 annual savings @ 3MW; $112,000 @ 8MW)
 Total annual savings of $239,000 @ 3MW; $635,000 @ 8MW)
 Lower losses = less cooling required

PUE – Power Usage Effectiveness
PUE =
Total Facility Power
IT Equipment Power
How PUE is changing the topologies, functions, and
characteristics of UPS in the data center space

More on PUE
» Power usage effectiveness (PUE) is a measure of how efficiently a
data center uses its power; specifically, how much of the power is
actually used by the computing equipment
» PUE is the inverse of data center infrastructure efficiency (DCIE).
» An ideal PUE is 1.0
» Anything that isn't considered a computing device in a data center
(i.e., lighting, cooling, etc.) falls into the category of facility power
usage

Value Propositions to Drive Lower PUE
» Medium Voltage Application
» Highly Efficient, Up to ~98%
» Minimal if any AC needed for the UPS, will operate up to 104 F without derating
» Half the heat rejection of legacy UPS
» No special room needed – less construction cost
» Power Dense – twice the power in half the space
» Lower overall maintenance cost
» Air side economizing for facility
