48 Vdc Distribution; a Safe, Practical and Efficient Solution for Equipment Racks

Vicor’s new AC Front End Module has an isolated, regulated output of 330 W at 48 Vdc. Its applications are many and varied, including powering rack-mounted equipment in telecommunications or data centres. However designers for such applications sometimes ask why the DC output has been set at 48 V rather than 12 V, or even 5 V?

First Direct 48V-to-Processor, Intel x86-compliant Solution

With increasing demands on datacenter and cloud computing infrastructure, efficient power management is a growing concern. Electricity costs can account for up to 50% of annual datacenter operating expenses. The 5% efficiency gain enabled by Vicor’s Intel compliant power solution can reduce per-processor power loss by 10W – or 30% – which can yield annual datacenter electricity savings of approximately $500,000 across 30,000 onsite processors.
