Description
Mean Well LRS-450 series is a 450W single-output enclosed type power supply with 35mm of low profile design. Adopting the input of 115VAC or 230VAC (select by switch), the entire series provides an output voltage line of 5V (Model No.: LRS-450-5), 12V(Model No.: LRS-450-12), 15V(Model No.: LRS-450-15), 24V(Model No.: LRS-450-24), 36V(Model No.: LRS-450-36) and 48V(Model No.: LRS-450-48).
In addition to the high efficiency up to 92%, with the built-in long life fanLRS-450 can work under -20~+70℃ with full load. LRS-450 has the complete protection functions and 5G anti-vibration capability; It is complied with complete international safety regulations LRS-450 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.
