Mean Well Introduces 40/60W Metal Case LED Power Supply

MEAN WELL introduced 40 and 60W lower wattage models – HLG-40H (40W) and HLG-60H (60W) – LED power supply series to fulfill the needs the middle to low wattage LED lighting applications. These two series have four options (A/B/blank/D type) in different mechanisms and input/output design. The A type have two holes on the cover which allows users to adjust dc output voltage range from 60 to 100% without opening the case; the B type equips with three in one dimming function (1-10Vdc, PWM, resistance). Through additional signal output cable, it is said to offer system designers great flexibility for dimming operation and energy saving design; D-type (optional) equips with timer dimming function. After powering on the system, the D type model will start up the internal timer controlled by the MCU with pre-set counting program that up to three different time period (four different brightness levels) can be set to adjust the output current in each period. According to customer’s request, the company can define auto brightness adjustment and the brightness level in each period by customizing the program. The last, the Blank type, has basic features without voltage and current adjustment function.

Featuring 90-305Vac wide range ac input, the HLG-40H/60H series are not only fit for general 115 or 230Vac main input, but also can be operated under 277Vac input in North America. Built-in two stage active PFC function, these new series comply with harmonic current limitation per EN61000-3-2 Class C (≥60% load). They also fulfill PF≥0.9 if loading over 60% and possess 4KV surge immunity (EN61000-4-5) ability which complies with the requirements of street lighting. With up-to date high efficiency topology, they possess up to 91% efficiency, so they can be cooled by free air convection from -4 to +70°C ambient temperature (-40°C power on at 230Vac and above) that meets the requirements of closed environment with high temperature. Besides standard functions of protections for short circuit, over voltage, over current, and over temperature, these power units comply with global certificates per UL/CUL/TUV/CB/CE including UL8750 and EN61347-2-13 of lighting regulations.
