» MV – LV Transformation at UPS 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

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

Major Savings in MV / 415V Distribution

PUE – Power Usage Effectiveness

How PUE is changing the topologies, functions, and characteristics of UPS in the data center space

10

PUE = Total Facility PowerIT Equipment Power

Active Power Proprietary & Confidential – © 2013 Active Power, Inc. 11Active Power Proprietary & Confidential – © 2013 Active Power, Inc. 11

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 de-rating

» 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
