■ Description
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,
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.

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. 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).
