Description
LRS-350 series is a 350W single-output enclosed type power supply with 30mm of
low profile design. Adopting the input of 11 SVAC 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°C 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 IEC/UL 62368-1. LRS-350 series serves
as a high price-to-performance power supply solution for various industrial
applications.

NOTE**|
-
All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25°C of ambient temperature.
-
Ripple & noise are measured at 20 MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1 uf & 47uf parallel capacitor.
-
Tolerance: includes set up tolerance, line regulation and load regulation.
-
Line regulation is measured from low line to high line at rated road.
-
Load regulation is measured from 0% to 100% rated load.
-
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.
-
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).
-
The ambient temperature derating of 5°C/1 000m is needed for operating altitude greater than 2000m (6500ft).
-
This power supply does not meet the harmonic current requirements outlined by BS EN/ENS 1000-3-2. 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
c) 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
Exception:
Power supplies used within the following end-devices do not need to fulfill 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
-
RCM is on voluntary basis and meets relevant JEC or AS/NZ.S standards complying with AS/NZS 4417.1.
