Description
Mean Well LRS-50 series is a 50W single-output enclosed type power supply with 30mm of low profile design. Adopting the full range 85~264VAC input, the entire series provides an output voltage line of 3.3V(Model No.: LRS-50-3.3), 5V(Model No.: LRS-50-5), 12V(Model No.: LRS-50-12), 15V(Model No.: LRS-50-15), 24V(Model No.: LRS-50-24), 36V(Model No.: LRS-50-36) and 48V(Model No.: LRS-50-48).
In addition to the high efficiency up to 90%, the design of metallic mesh case enhances the heat dissipation of LRS-50 that the whole series operates from -30℃ through 70℃ under air convection without a fan. Delivering an extremely low no load power consumption (less than 0.2W), it allows the end system to easily meet the worldwide energy requirement. LRS-50 has the complete protection functions and 5G anti-vibration capability; it is complied with the international safety regulations such as TUV BS EN/EN62368-1, BS EN/EN60335-1,BS EN/EN61558-1/-2-16, UL62368-1 and GB4943. LRS-50 series serves as a high price-to-performance power supply solution for various industrial applications.
In LRS Family, there are LRS-35 series, LRS-50 series, LRS-75 series, LRS-100 series, LRS-150F series, LRS-150 series, LRS-200 series, LRS-350 series, LRS-450 series, LRS-600 series.
