The Green Grid Offers a Perspective on Eco Mode, Explores Energy Efficiency Gains And Economic Benefits For Data Centers
The Green Grid has published a new white paper titled Evaluation of Eco Mode in Uninterruptible Power Supply Systems. The paper offers an extensive look into how Eco Mode can improve data center efficiency and overall Power Usage Effectiveness (PUE) when appropriately deployed, and makes recommendations regarding other power distribution equipment to ensure a reliable power system. The full contents are free and available to the public on The Green Grid's website.

Uninterruptible Power Supply (UPS) Eco Mode is one of The Green Grid Data Center Maturity Model's (DCMM) energy saving recommendations and can increase overall efficiency when implemented correctly. 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 center operators understand Eco Mode from the ground up.
"Our goal was to deliver an Eco Mode white paper that was detailed, well-defined and easily digestible for the IT community or anyone looking to increase data center efficiency," said Unmesh Agarwala, Juniper Networks representative and Board member of The Green Grid. "The Green Grid, with the help of the industry, has accomplished this by addressing relevant questions and concerns around Eco Mode, such as how it interacts with new technology and when — or even if — it should be implemented."

The paper addresses two key points for data center owners and operators to consider before implementing Eco Mode technology Power Distribution and Utility Power Quality.
Power Distribution – It is extremely important to match switch-over time for an Eco Mode UPS to the power supply ride-through or static switch time. Data center operators should analyze the power distribution within their data centers and consult their UPS manufacturers for information prior to implementing Eco Mode.
Utility Power Quality – UPS Eco Mode requires an acceptable level of utility power quality and it must be within the voltage tolerance of all equipment to keep the UPS operating in the most efficient range possible. Additional details are included in the paper about moving from Level 1 UPS Eco Mode to Level 3.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
