Microsemi Introduces Energy-efficient PoE (EEPoE) Midspans
January 31, 2012
Microsemi Corp. announced its new high-efficiency Power-over-Ethernet (PoE) midspans. According to the company, the new PoE devices reduce energy consumption on network cables by as much as 50 percent compared to alternative midspans and PoE network switches. The Microsemi PowerDsine® PD-5524G EEPoE midspan complies with IEEE802.3at 2009 standards for delivering up to 30W of power to network devices including IP cameras, access control systems and thin clients, over the same standard CAT5 cabling as data.

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.
