Meanwell's LRS-50 series is a 50W single-output enclosed type power supply with 30mm of low profile design. The AC input is  85-264VAC which could be directly supplied from the house supplied voltage. The output from SMPS will be 5V.  The SMPS has high efficiency of up to 83%, the design is of a metallic mesh case that enhances the heat dissipation of  LRS-50 that the whole series operates from -30°C through 70°C under air convection without a fan. It has extremely low no-load power consumption (less than 0.2W), which allows the end system to easily meet the worldwide energy requirement. Meanwell's LRS-50 SMPS has complete protection functions and 5G anti-vibration capability; it complies with international safety regulations such as TUV EN60950-1, EN60335-1, EN61558-1/-2-16, UL60950-1 and GB4943. LRS-50 series can be used for many purposes with the best performance from it.
