In response to the demand of LED lighting, following the successful launch of 18~150W LED power supply, MEAN WELL added two new series HLG-240 and HLG-240H to its high IP level product family in order to fulfill the higher wattage requirements in the market. With built-in active PFC function, the HLG-240H series features 90~305VAC wide range AC input (90~264VAC for HLG-240), thus not only meets the harmonic current limitation per EN61000-3-2 Class C, HLG-240(H), but fulfills PF>0.9 if loading over 65%. In addition, these two power units possess 4KV surge immunity (EN61000-4-5) ability which complies with the requirements of streetlighting.

The major characteristic of the two series is fully potted by heat-dissipating glue, so they can reach IP 65 or IP67 waterproof/ dustproof level. In the meantime, users can adjust DC output voltage range from 95 to 105% and current range from 50 to 100% by the following methods: A and C type by removing the rubber stopper on the cover, and B type by adjusting through the output cable. This flexibility can fulfill the demands of LED lighting system designers when they need some slight adjustment of output voltage and current.

With up-to date LLC and synchronize rectify technology, HLG-240(H) posses up to 94% of high efficiency, so it can be cooled by free air convection from -30℃ to +70℃ ambient temperature and meets the requirements of outdoor assembly. Beside standard functions of protections for short circuit, over voltage, overload, and over temperature, HLG-240(H) has four options (A/B/C/blank type) in different mechanisms and input/output design for selection. I/O connection can be changed by output cable or terminal block, which allows users a flexible installation in various systems.
