Rugged 350 W AC-DC Power Supplies Comply with SEMI-F47 Requirements
XP Power announced the SHP350 series of single output rugged 350 W AC-DC power supplies aimed at industrial applications. Meeting the SEMI F47 Voltage Sag Immunity Standard for factory automation equipment, especially relevant to the production of semiconductors, the SHP350 can assure the required output voltage and current will be maintained in the event of a sag in AC input voltage below specified limits. Achieving a high power density of 6.6 Watts per cubic inch and with a typical efficiency of 85%, these compact fan-cooled units measure only 7.0 x 3.6 x 2.1 inches (177.8 x 91.44 x 53.34 mm).
The series comprises six single output models providing the popular nominal output voltages from +12 to +48 VDC. The output is also capable of being adjusted within +/- 10% in order to cater for any non-standard voltage applications. A remote sense facility compensates for a voltage drop of up to 0.5 V due to line losses. An auxiliary output provides an always-on +5 VDC / 0.2 A output suitable for powering memory, logic or control functions. The supplies accept the full universal input range from 85 to 264 VAC.
When operated at high-line input voltages above 180 VAC, the SHP350 has a peak power capability that can deliver up to 420 Watts output for up to 10 seconds. The ability to momentarily provide a higher output power is ideal for applications, such as motor start-up, where increased power is very occasionally required. Customers need not design in a higher wattage power supply thus saving additional cost and valuable board space.
Control signals include AC OK/power fail and a remote On/Off input. A single wire current sharing facility allows the addition of extra units to provide an overall higher power output or to configure redundant units.
The SHP350 can operate over a wide temperature range of -20 to + 70 degrees C, with no derating until +50 degrees C and offers start up from -40 degrees C. The units are internally cooled and employ a variable speed fan to assist in audible noise reduction. The units also meet the IT equipment safety specification UL/EN 60950-1 and comply with the EN55011 / EN55022 level B standard for conducted emissions without the need for additional filtering components.
Opinion: Unraveling the Ultra-Low Power Design Issues
The SHP350 compliments two higher output power ranges of 650W and 1000W currently available within the SHP family. Pricing for the SHP350 is $152.10 for 500 unit orders and is available from Newark or direct from XP Power.

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.
