Excelsys Offers Low Profile 200W LED Power Supply
The LDB200 series of LED power supplies from Excelsys offer 200W of Constant Current/Constant Voltage power in an IP67 rated, low profile, aluminum case measuring only 7.80 x 2.48 x 1.38" with UL8750 and EN61347 safety approvals.
The LDB200 series consists of two standard models offering 24 or 48V nominal output voltages. The units offer constant voltage operation up to their full load capability and then constant current operation down to 50% of their nominal output voltage. An extended universal ac input range of 90-305Vac with active power factor correction and high efficiency operation up to 92.5% make these units ideal for "green" lighting applications around the globe. Additional features include: -30 to +70°C operating temperature; built-in OCP/OVP/OTP/SCP protection; tight line and load regulation; and an MTBF of 1 million hours per Telecordia SR-33. Custom output voltage and output current setpoints are available for OEM applications.
The LDB200 power supplies are available now with evaluation quantities available from stock and manufacturing lead times of 8-12 weeks. Standard pricing is as low as $100 for 100 pieces.

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.
