Qingdao350W Single Output Switching Power Supply
LRS-350 series is a 350W single-output enclosed type power supply with 30mm of low profile design. Adoptingthe input of 1 15VAC or 230VAC (select by switch), the entire series provides an output voltage line of 3.3V4.2V,5V,12V,15V,24V, 36V and 48V.
In addition to the high efficiency up to 89%, with the built-in long life fan LRS-350 can work under -25~+70'℃ with full load. Delivering an extremely low no load power consumption (less than 0.75W), it allowsthe end system to easily meet the worldwide energy requirement. LRS-350 has the complete protectionfunctions and 5G anti-vibration capability: it is complied with the international safety regulations such asIEC/UL 62368-1.LR$-350 series serves as a high price-to-performance power supply solution forvariousindustrial applications.
