Murata 162W 54Vout Half-Brick Power Module Suits PoE Applications
The Murata Power Solutions EMH Series dc-dc power converter module provides a 54V SELV output, 2250Vdc isolation and a Basic insulation system meeting the requirements for multiport IEEE 802.3at (PoE+) applications. The EMH-54/3-Q48N-C can deliver 30+ watts of power at 54V to each of four PoE+ Ethernet ports or can deliver up to 162 watts to loads requiring 54V.
The EMH was specifically designed for use in applications requiring a wide operating voltage range such as battery-powered systems (24, 48 or 60V) and wireless base-station applications. The modules accommodate a Vin range of 18 to 72Vdc suitable for applications across all regions of the world.
The EMH-54/3-Q48N Series can be mechanically configured to operate in applications that require forced air cooling or "sealed box" applications, by offering an open frame module for forced air cooling or adding an optional baseplate for mounting a heat sink or for conduction cooling in a "sealed box" application.

This highly functional, multipurpose dc to dc converter delivers 54V @ 3A over a wide operating input voltage range of 18 - 72V with efficiencies up to 91.5%. The modules are UL approved for PoE applications requiring a dc-dc module that will deliver a 54V SELV output with a basic insulation system that has an isolation voltage rating of 2250Vdc. The module conforms to the Industry Standard, DOSA half-brick package measuring 58.4 x 61 x 12.7mm (2.3 x 2.4 x 0.5 inches). An optional baseplate can be supplied if the application requires a heat sink, or for use in conduction cooling (sealed box) applications. Added protection features include input under voltage lockout, output current limiting, short-circuit protection, and thermal shutdown.

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.
