Description 

LRS- 350 series is a 350 W single-output enclosed type power supply with 30 mm of low profile design . Adopting  the input of 115 VAC or 230VAC (selected 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 requirements .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.

Note 

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 line.

5.Load regulation is measure from 0% to 100% rated load.

6. Length of se 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 ℃ /100m is needed for operating altitude greater than 200m(6500 ft).
