Mean Well Adds High-Input-Voltage LED Power Supplies to Offering
After the successful launch of the HVG(C)-100 (100W) series LED power supplies, Mean Well has announced the more powerful HVG(C)-150 series of 150W ac-dc high input voltage LED power supply, in order to fulfill the higher wattage requirements for LED lighting applications. Compared with HVG(C)-100, the input voltage range of HVG(C)-150 had been increased to 180~528VAC, thus, they are fit for the general 230VAC main input, and also can be operated under 347/440/480VAC input in USA, Japan, and Canada.
Designed with constant voltage (C.V.) plus constant current (C.C.) mode, HVG-150 series are low voltage output models (54VDC Max.) while HVGC-150 are high voltage output models (428VDC Max.). Both series are built-in two-stage PFC function, so that they can meet the harmonic current limitation per EN61000-3-2 Class C (>50~55% load), and they also fulfill PF>0.9 if loading over 50% (>70% load under 480VAC). In addition, they possess 4KV surge immunity (EN61000-4-5) ability which complies with the requirements of street lighting.
HVG(C)-150 has three options (A/B/D type) in different mechanisms and functions for your selection. In A type of HVG-150, users can adjust DC current range from 50% to 100% and output voltage ±10% by removing the rubber stopper on the cover. In A type of HVGC-150, users can adjust DC current range from 60% to 100%; B type models equip with three-in-one dimming function (0~10VDC, PWM, resistance) while D type models (optional) equip with "multiple stage timer dimming" function that can be customized by request.

In addition, these two series possess up to 91.5% of high efficiency, so they can be cooled by free air convection from -40°C to +70°C ambient temperature and meet the high ambient temperature requirements for closed systems. In order to fit in with the outdoor harsh environment, aluminum case with fully potted by glue (IP65/67 structure) are also designed in these new power units.
Beside standard functions of protections for short circuit, over voltage, overload, and over temperature, HVG(C)150 comply with global certificates per UL/CUL/FCC for HVG-150 and UL/CUL/TUV/CB/FCC/CE for HVGC-150, including UL8750 and EN61347-2-13 of lighting regulations. They are very suitable to be used in LED street lighting, LED high bay lighting, LED outdoor lighting and parking lot lighting, etc.

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.
