EMerge Alliance Completes New Data/Telecom Center 380VDC Power Standard
The EMerge Alliance announced the completion of the EMerge Alliance Data/Telecom Center Standard. The new standard creates an integrated, open platform for power, infrastructure, peripheral device and control applications to facilitate the hybrid use of AC and DC power within data centers and telecommunications central offices. This change in power distribution architecture involves making a single conversion of the incoming line of AC voltage to 380VDC, and then distributing it directly to rack-mounted ICT equipment, simplifying the otherwise unnecessarily complex power management provisions generally used in today's AC-powered data centers.
According to Dennis Symanski, senior project manager at the Electric Power Research Institute (EPRI) and chair of the Alliance's technical standard committee for data and telecommunications centers, using DC power distribution in data centers significantly improves reliability and reduces equipment and operating costs.
"The benefits are clear. By requiring fewer components and conversions than their AC counterparts, DC power systems in data centers suffer fewer heat related failures and require less space, energy, and maintenance to operate," said Symanski. "DC power collection and distribution systems also simplify the use of locally generated power, providing an effective integration of on-site energy generation and storage with direct delivery of controlled power."

"The EMerge Alliance Data/Telecom Standard was designed to integrate with our other standards to form a family of area-specific DC microgrids that, when interconnected, create a resilient and versatile building or campus energy network," said Alliance Chairman Brian Patterson. "DC power is a key component in net-zero-energy buildings, and our growing organization of more than 100 members continues to make progress with standards for the occupied space, data and telecommunications centers, building services, and outdoor applications to achieve our vision for improved energy efficiency, flexibility and sustainability throughout buildings."

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.
