■ Description
LRS-75 series is a 75W single-output enclosed type power supply with 30mm of low profile design. Adopting
the full range 85~264VAC input, the entire series provides an output voltage line of 5V, 12V, 15V, 24V,
36V and 48V.
In addition to the high efficiency up to 91.5%, the design of metallic mesh case enhances the heat dissipation
of LRS-75 that the whole series operates from -30 through 70 under air convection without a fa n. ℃℃
Delivering an extremely low no load power consumption (less than 0.3W), it allows the end system to
easily meet the worldwide energy requirement. LRS-75 has the complete protection functions and 5G antivibration capability; it is complied with the international safety regulations such as
TUV EN60950-1,
EN60335-1,EN61558-1/-2-16, UL60950-1 and GB4943. LRS-75 series serves as a h igh price-to-
performance power supply solution for various industrial applications.

PACKING
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 ambient temperature derating of 5 /1000m is needed for operating altitude greater than 2000m(6500ft).
8. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by
mounting the unit on a mm* mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets 360 360
EMC directives. For guidance on how to perform these EMC tests, please refer to EMI testing of component power supplies.
