HLG-150H-24A is a 150W LED AC to DC power supply with constant current output and constant voltage output design as its main features It can work at an input voltage of 90~305VAC. It has a high conversion efficiency of up to 94%. It adopts a fanless design and can work under natural air cooling Metal shell and IP67IIP65 high protection grade design suitable for indoor or outdoor applications. Can be used for LED street lighting, LED overhead lighting, parking lot lighting, LED fishing lights, LED greenhouse lighting.
