Green Grid white paper offers fresh perspective on UPS ‘eco mode’ for data centres

Fri, 01/11/2013 - 17:36 -- Ruth Williams

The Green Grid has published a white paper on how Eco Mode can improve data centre efficiency and overall Power Usage Effectiveness (PUE) when appropriately deployed.

The paper, Evaluation of Eco Mode in Uninterruptible Power Supply Systems, offers an extensive look into UPS systems, and makes recommendations to data centre managers regarding other power distribution equipment to ensure a reliable power system.  

In order to help understand and deploy what is typically the highest-efficiency mode, the white paper breaks down key elements such as UPS technology and performance, critical power systems configuration, IT power supply ride-through, and utility grid reliability. The white paper explores each of these ideas and their trade-offs, helping data centre operators understand Eco Mode from the ground up.

According to The Green Grid, transfer-time is “one of the most salient performance characteristics for eco mode.” This is the amount of time during which the UPS will not output any power.
