Mean Well Announces New Series of 240W Slim DIN Rail Type Power Supplies with Wide Range Input
MEAN WELL introduced a new 240W ac-dc slim DIN rail power supply featuring a wide input range for both single and two phase power systems (the WDR-240 series) to complete their WDR product line. Equipped with a 180 to 550Vac wide input range, the WDR-240 can be used in general power systems with a single phase 230Vac input or can capture any two phases from the 330~550Vac three-phase power system, which can greatly increase the flexibility of system deployment.
With up-to date high efficiency circuit design, the WDR-240 series possess up to 91% efficiency and can provide 240W continuously up to 50° by only free air convection, or operate under 70° ambient temperature by suitable power derating. The slim design of 63mm in width helps save the precious space on the rail and also makes it 43.2% smaller in size compare to its predecessor model DRT-240 (240W). Meanwhile, the WDR-240 also has 2% higher efficiency than the corresponding DRT-240 models. In addition, in order to be operated normally in frozen areas, they are equipped with low temperature power-on ability at -30°C, which is better than the DRT-240 at -20°C. Other standard functions include DC OK relay contact alarm signal output, front panel LED indicator, front panel DC voltage adjustment , as well as protection for short-circuit, overload, over voltage, and over temperature. WDR-240 series comply with UL/CB/CE certificates and also meet the EMC requirements of heavy industry immunity level (EN61000-6-2). Suitable applications include an industrial control system, semi-conductor fabrication equipment, factory automation, electro-mechanical applications, and marine related installation.

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.
