As the quest for efficiency continues it becomes apparent that what worked in the past needs improvement. More and more data center managers are looking at alternate power plans to distribute electricity through their facility. One such strategy in North America is to minimize the inefficient and costly transformers used to convert the high 480 volt AC power coming into the building to the lower 200-240 volt power needed for IT equipment.
By bringing 480 volt power directly to the rack all transformers can be eliminated, improving efficiency by several percent. This can save hundreds of thousands of dollars in the construction or expansion of data centers while continuing to save even more in monthly operational costs.
