Product Details

Mean Well LRS Switch Mode Power Supply

LRS-100 series is a 100W 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 3.3V, 5V, 12V, 15V, 24V, 36V and 48V.

In addition to the high efficiency up to 91%, the design of metallic mesh case enhances the heat dissipation of LRS-100 that the whole series operates from -30℃ through 70℃ under air convection without a fan. 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-100 has the complete protection functions and 5G anti-vibration capability; it is complied with the international safety regulations such as TUV BS EN/EN2368-1,BS EN/ EN60335- 1, BS EN/ EN61558- 1/- 2- 16, UL62368- 1 and GB4943. LRS- 100 series serves as a high price- to- performance power supply solution for various industrial applications.

PACKING 0.34Kg ; 40pcs/14.6Kg/0.92CUFT
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 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 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives.
