Description
Mean Well LRS-350 series is a 350W single-output enclosed type power supply with 30mm of low profile design. Adopting the input of 115VAC or 230VAC (select by switch), the entire series provides an output voltage line of 3.3V(Model No.: LRS-350-3.3), 4.2V(Model No.: LRS-350-4.2), 5V(Model No.: LRS-350-5), 12V(Model No.: LRS-350-12), 15V(Model No.: LRS-350-15), 24V(Model No.: LRS-350-24), 36V(Model No.: LRS-350-36) and 48V(Model No.: LRS-350-48).
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 allows the end system to easily meet the worldwide energy requirement. LRS-350 has the complete protection functions and 5G anti-vibration capability; it is complied with the international safety regulations such as IEC/UL 62368-1. LRS-350 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.
