80 Watt LED power supply
June 2011
Electrical Power & Protection
Mean Well has introduced an 80 W switch mode power supply – HLG-80H series – to fulfil the need for middle to low power LED lighting applications. Featuring 90-305 VAC input range, HLG-80H series is suitable for general 115 or 230 VAC mains input and can also be operated under 277 VAC input in North America. HLG-80H has three options (A/B/Blank type) in different housings with a selection of input/output design. A fully potted type (using heat dissipating glue) reaches IP65 protection level.
Users can adjust DC output voltage from 90 to 110% and current from 60 to 100%. The B-type is equipped with a three-in-one dimming function (1-10 VDC, PWM or resistance). Through an additional signal output, system designers are offered great flexibility for dimming and energy saving. The Blank type has the basic features without voltage and current adjustment functions.
With built-in active PFC, the supplies comply with harmonic current limitation per EN61000-3-2 Class C. They also possess 4 kV surge immunity (EN61000-4-5) which complies with the requirements for street lighting. Using up-to-date high efficiency topology, HLG-80H possesses efficiency up to 91%, allowing it to operate using only free air convection cooling from -4 to +70°C ambient temperature. Beside the standard functions of short circuit, over-voltage, overload and over-temperature protection, the units comply with global certification per UL/CUL/TUV/CB/CE. Suitable applications include LED street lighting, LED tunnel lighting, outdoor LED displays and LED decorative lighting. They are also good solutions for general industrial applications in outdoor environments with high dust and moisture.
