Electrical Power & Protection
In response to the demand for LED lighting and outdoor architecture decoration MEAN WELL has added the HLG-240 and HLG-240H to its product family in order to fulfil higher wattage requirements in the market. With built-in active power factor correction and wide AC input, 90-305 V (HLG – 240H) and 90-264 V (HLG-240), the supplies meet the harmonic current limitation per EN61000-3-2 Class C at a PF>0,9 if loading is over 65%. In addition, the units possess 4 kV surge immunity (EN61000-4-5) which complies with the requirements of street lighting.
The transformers have been fully potted with heat-dissipating glue to reach IP65 or IP67 waterproof/dustproof levels. The DC output voltage is adjustable from 95 to 105% (full scale) and the current from 50 to 100% to add flexibility for LED lighting system designers. In order to meet harsh outdoor requirements the supplies have been packaged in a full-aluminium case.
Up-to date rectifier technology enables efficiencies of 94% allowing cooling by free air convection from -30 to +70°C ambient for outdoor assembly. Standard functionality includes protection for short circuit, over voltage, overload, and over temperature. I/O connection can be changed by output cable or terminal block, to give users flexible installation options. HLG-240(H) series comply with global certificates per UL1012, EN61347-1, EN61347-2-13 (lighting regulations) as well as UL60950, EN60950-1 (IT regulations). These high efficiency power supplies are suitable for LED street lighting, outdoor displays and LED decorative lighting in applications that require high resistance to dust and moisture.
