MEAN WELL launches PLP-45W PCB Type LED Power Supply

After introducing LED power supplies with aluminum casing (CLG family) and fully enclosed plastic casing (PLN, PLC, ELN, LP family), MEAN WELL launched another LED product category, AC/DC open frame type for the “low cost” and “built-in” installation of LED lighting related applications. With the new PLP-45(45W), in addition to its existing PLP-30(30W) and PLP-60(60W) series, MEAN WELL offers LED system designers three different wattage options – 30W, 45W and 60W, which fully satisfies the low power wattage required. Featuring 90~264VAC full range input and built-in active PFC function, PLP-45 series complies with EN61000-3-2 Class C (harmonic current) and PF>0.9 when output loading is higher than 75%, fulfilling the general requirement of lighting fixtures.

Thanks to the simplified single stage PFC topology, the required high power factor can be achieved economically. Efficiency of PLP-45 series is as high as 89% and hence can operate at full load between -30℃ and +60℃ by only free air convection, the ambient temperature maxes at 70℃, which is often requested by lighting systems. Through adjustment of built-in potential meter, output current level of the PSU can be fine tuned between 75~100% rated value to comply with the requirement of LED characteristics. Other standard functions include short circuit, over load, and over voltage protections.

Based on the case-less and 4”x2” miniature PCB design, typical applications for these new PCB type LED driver units include general indoor LED lighting, LED-based decorative lighting, and LED electrical display which has its own system casing.
