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 of up to 89%, with the built-in long-life fan LRS-350 can work under -25 +70’C with a 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 complete protection functions and 5G anti-vibration capability: it complies with 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.

NOTE
| 1. All parameters NOI specially mentioned are measured at 230VAC input,
rated load and 25 of ambient temperature.
2. Hipple & noise are measured at 20MHz of bandwidth by using a 12 twisted
pair-wire terminated with an O.1uf & 47ut parallel capacitor.
3. Tolerance: includes set up tolerance, line regulation, and load
regulation.
4. Line regulation is measured from the low line to the high line at the
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 ONOFF 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 C/1000m is needed for operating
altitude greater than 2000m(6500ft).
9. This power supply does not meet the harmonic current requirements outined
by BS EN/EN61000-3-2. Please do not use this power supply
under the following conditions:
a) the end-devices is used within the European Union, and
b) the end-devices is connected to public mains supply with 220Vac or greater
rated nominal voltage, and
)the power supply iS:
installed in end-devices with average or continuous input power greater than
75W, or
belong to part of a lighting system rom Arrow.c
EXception:
Power supplies used within the following end-devices do not need to fufill BS
EN/EN61000-3-2
a) professional equipment with a total rated input power greater than 1000W;
b) symmetrically controlled heating elements with a rated power less than or
equal to 200w
