DC/DC Converters for Curved, Uneven or Thermally Non-conductive Surfaces
ABSOPULSE Electronics' BAP 236TH Series dc/dc converters generate up to 250W output power. Cooling is by heat-sink fins on the top of the units - no fans and no attachment to a heat-sinking surface are required. The converters can be installed on curved, uneven and non-conductive surfaces, such as plastic, and are ideal for installation on the curved surfaces of vehicles or machine chassis. They have generous design headroom and are rated for operation over a -20oC to +50oC temperature range for full specification. The units comply with EN/UL60950 and equivalent industrial safety standards. A railway grade version which meets EN50155 is also available.

These converters operate from inputs of 24V (21-30V), 48V (42-60V) or 125V (105-145V) and provide tightly regulated outputs of 24V, 48V or 125Vdc. Other input/output configurations are available on request. An optional built-in redundancy diode allows for paralleling and N+1 operation. The redundancy diode also allows for connection to a back-up battery. Efficiency is 85% at full load, depending on the input/output configuration.
The converters are filtered to meet EN55022 Class B conducted and radiated requirements. Protection features include 2250Vdc input/output isolation, overload, over-voltage and short circuit protection with thermal shutdown and self-resetting. An output fail alarm (Form C) is available as an option. Other options include conformal coating, heavy ruggedizing and extended temperature ranges. The units are housed in compact, ruggedly constructed 113 x 115 x 261mm chassis-mount enclosures.

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.
