Date Announced: 11 Aug 2011 After launching the new generation of high efficiency metal case LED power supplies at lower wattage range ~ HLG-80H (80W)/ HLG-100(H)/ 100W, HLG-120 (H)/120W, HLG-150(H)/150W, HLG-185(H)/185W, and HLG-240(H)/240W series, Mean Well continuously introduced the 320W models~HLG-320H series, to fulfill the demands of high wattage LED lighting applications. Featuring 90~305VAC wide AC input range, HLG-320H series not only is fit for general 115VAC or 230VAC main input, but also can be operated under 277VAC input in North America. HLG-320H has five options (A/B/C/D/blank type) in different mechanisms and functions for your selection. 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. 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.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. Standard functions include protections for short circuit, over voltage, overload, and over temperature. These 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. 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. They are also good solutions for general applications at outdoor environment with high dust and moisture, such as outdoor mechanical or electrical equipments, base station of telecommunication…etc. Besides, they comply with global certificates per UL/CUL/TUV/CB/CE including UL8750, EN61347-1, and EN61347-2-13 lighting related regulations, which can greatly guarantee your operation safety.Features:1.Wide range input 90~305VAC 2.Aluminum case and potted by glue, comply with IP65/67 3.Output voltage and current adjustable (selected models, please refer to the table below) 4.Meet 4KV surge immunity level (EN61000-4-5) 5.Built-in active PFC function, comply with EN61000-3-2 harmonic Class C (>50% load) 6.95% extremely high efficiency 7.3 in 1 dimming function: 1~10VDC / PWM signal / resistance (B type) 8.Cooling by free air convection 9.Protections: Short circuit/Overload /Over voltage/Over temperature 10.Certificates: UL / CUL / TUV / CB / CE 11.Dimension(LxWxH): 252x 90x 43.8mm(A/B/D/blank-type); 256x 90x 43.8mm(C-type) 12.5 years warranty
