According to a recent publication on Datacenter Dynamics, current estimates are that by 2025 data centers will consume one-fifth of all the electricity produced worldwide. To control their destinies, major builders of data centers are committing to building renewable power generation facilities along with their data centers. Thereby they lessen the strain on the local utilities and help them meet local, state, and federal requirements for renewable energy production.
Although many alternative energy production technologies initially produce direct current (DC), alternating current (AC) continues to power IT racks within data centers. This approach helps to minimize conversion losses, distribution losses, and the size of copper cabling needed for power. It enables maximum power density for the rack, resulting in a more energy-efficient data center.
Whether your data center is using renewable energy or not, AC is still the primary infeed to a data center. For those data centers electing to remain with this conventional approach, an intelligent PDU that supports an infeed of 415VAC 3-phase Wye can deliver 240VAC to the outlet without requiring a transformer in the PDU. This helps to minimize conversion losses, distribution losses, the size of copper cabling needed for power and enables maximum power density for the rack, resulting in a greener, more efficient data center.
