What it is
White paper examining 415 VAC 3-phase power distribution deployed to rack level in North American data centers. Discusses reducing number of transformers and converters in power path from building entrance to IT loads to improve efficiency, reduce electrical costs, and address rising power densities.
Why it matters
As power densities rise and availability decreases, facilities teams must choose between costly specialty infrastructure or alternative distribution architectures. This voltage approach reduces upfront capital, power consumption, and floor space by eliminating transformation steps, directly affecting design decisions for high-density deployments.
Evidence from source:
- Discusses deploying 415V 3-phase AC power to the rack to maximize physical and power density without specialty infrastructure
- Reducing number of transformers and operating at higher voltage improves efficiency and reduces electrical costs
- Alternative approach reduces upfront capital costs, power consumption and floor space in North American data centers
