|MEAN WELL has launched a new generation of high efficiency metal case LED power supplies to fulfill the demands of high wattage LED lighting applications, the 320W models~HLG-320H series. The HLG-320H series not only fit for general 115VAC or 230VAC main input, but also can be operated under 277VAC input in North America. With up-to date LLC topology and synchronous rectifier technology, HLG-320H possesses up to 95% of extremely high efficiency, so it can be cooled by free air convection from -40℃ to +70℃ ambient temperature that meets the requirements of outdoor installation. These high efficiency power supplies are very suitable for LED street lighting, LED high-bay lighting, outdoor electronic display, LED decorative lighting, indoor/outdoor LED lighting…etc. In addition, in order to fit in with the outdoor harsh environment, aluminum case and stainless screws are designed in these new 320W LED power supplies.
Standard functions include protections for short circuit, over voltage, overload, and over temperature. The HLG-320H power units have five options (A/B/C/D/blank type) in different mechanisms and input/output designs that I/O connection can be cable type or terminal block, which allows users a flexible installation in various systems. For A/C type designs, users can adjust DC output voltage range from 90% to 110% and current range from 50% to 100% by removing the rubber stopper on the cover; B type equips with three-in-one dimming function (1~10VDC, PWM, resistance) and D type (optional) equips with “multiple stage timer dimming” function that can be customized by request; while Blank type has basic features without voltage and current adjustment function.
