Adopting the input of 115VAC or 230VAC (select by switch), the entire series provides an output voltage line of 3.3V, 4.2V, 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 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 UL60950-1. LRS-350 series serves as a high price-to-performance power supply solution for various industrial applications. ■ Model Encoding LRS - 350 - 3.3 Output voltage Output power Series name File Name:LRS-350-SPEC 2015-12-31 LRS-350 350W Single Output Switching Power Supply series SPECIFICATION LRS-350-3.3 LRS-350-4.2 LRS-350-5 LRS-350-12 LRS-350-15 LRS-350-24 LRS-350-36 LRS-350-48 DC VOLTAGE 3.3V 4.2V 5V 12V 15V 24V 36V 48V RATED CURRENT 60A 60A 60A 29A 23.2A 14.6A 9.7A 7.3A CURRENT RANGE 0 ~ 60A 0 ~ 60A 0 ~ 60A 0 ~ 29A 0 ~ 23.2A 0 ~ 14.6A 0 ~ 9.7A 0 ~ 7.3A RATED POWER 198W 252W 300W 348W 348W 350.4W 349.2W 350.4W RIPPLE & NOISE (max.)

Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance : includes set up tolerance, line regulation and load regulation. 4. Line regulation is measured from low line to high line at rated load. 5. Load regulation is measured from 0% to 100% rated load. 6. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time. 7.The 150% peak load capability is built in for up to 1 second for 12~48V.LRS-350 will enter hiccup mode if the peak load is delivered for over 1 second and will recover once it resumes to the rated current level(115VAC/230VAC). 8. The ambient temperature derating of 5℃/1000m is needed for operating altitude greater than 2000m(6500ft).
