16/25 W plastic case LED power supply
July 2012
Electrical Power & Protection
After launching the plastic case LED power supplies LPF-40/60/90 series, Mean Well has introduced the 16/25 W lower wattage range to fulfil the low power requirements for decorative lighting applications. Featuring 90-305 VAC input range, these supplies are not only fit for general 115 or 230 VAC mains input, but can also be operated under 277 VAC input in North America. Without dimming function, LPF-16/25 series are primary models with only basic functionality. More sophisticated, the 16D/25D series are equipped with additional three-in-one dimming that offers system designers greater flexibility when designing lighting fixtures. By using the 1-10 VDC, PWM signal or changing the resistance, brightness reduction and energy saving can be achieved.
The supplies are enclosed in a plastic case with 94V-0 fire prevention level. The LPF-16 (D) series provides two additional choices: standard type without IP rating and optional type with IP67. LPF-25 (D) series are fully potted in heat-conductive glue (IP67 structure) that allows internal shock absorption to 5G and provides protection for the internal electronic components against dust and moisture. In addition, the devices possess up to 87% efficiency and can work between -40 and 70°C using only free air convection for cooling. Other standard functions include Class II AC input design (two wires, without FG) and protection for short circuit, over voltage, overload and over temperature. Suitable applications include LED office lighting, LED electric displays, wash-wall lighting, LED stage lighting and LED decorative lighting.
