LRS-35 Enclosed Switching Power Supply

Description：

 

LRS-35 series is a 35W 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 5V,12V,15V,24V,36V and 48V.

In addition to the high efficiency up to 89%,the design of metallic mesh case enhances the heat dissipation of LRS-35 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-35 has the complete protection functions and 5G anti-vibration capability;it is complied with the international safety regulations such as TUV EN62368-1,EN60335-1,EN61558-1/-2-16,UL62368-1 and GB4943.LRS-35 series serves as a high price-to-performance power supply solution for various industrial applications.
