Agenda

Data Center Trends and Emerging Technologies

Gains with 400V DC in Data Center and Telecom Center

400VDC pilot installations

400VDC Eco-system availability

400VDC power portfolio availability


Data Center Landscape Changing

3

Different compute models available (enterprise, cloud, hyper-scale, co-location)

Demands for data and connectivity increase daily

Segmentation of computing applications

Green data center operations objectives

Customers have choices like never before


Convergence Creating Choices

Convergence creates several power choices


AC Power in Data Centers

30+ years of history

Established ecosystem

Highly reliable and efficient platform

Will be a choice of many customers for years to come


400V DC – widely discussed and considered in several applications

Data Centers High availability, high efficiency and lower total costs thanks to a simple architecture

Telecom sites Copper savings for telecom central offices lowers investment and installation costs

Commercial buildings / Micro grids Easy integration of renewable energy sources with a common 400V DC bus


400VDC drivers in Data Centers

Source: NTT-Facilities

Higher availability vs. AC UPS > 6x, due to more simple architecture

Increased overall efficiency, 8-12% (less conversion stages)

Lower footprint, ≈ 30%

More simple architecture - Data center loads are DC loads - Unnecessary conversions

AC/DC, DC/AC are eliminated

Easier integration with Renewable


400VDC drivers in Telecom (48V)

Key driver - Copper cable saving, 10x

Long distance power feeding (50 x lower distribution losses)

Similar architecture to 48V

2-4% higher overall efficiency


400VDC drivers in Commercial Buildings and Micro Grids

Energy sourcing becomes decentralized

- Local “green” production is typically DC

Connecting local sources to AC grid cost energy and money

- Part of the “green” energy is lost in conversions before it reaches any “real” load

- DC is converted to AC and back to DC

Sharing DC bus by different sources is much simpler than AC grid

- No phase/voltage balancing
