Overview

LRS-50-5 is the 5V output model of this series: rated current 10A, rated power 50W, typical efficiency 83%.

LRS-50 series is a 50W single-output enclosed type power supply with 30mm of low profile design. Adopoting 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 90%, the design of metallic mesh case enhances the heat dissiptation of LRS-50 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 0.2W), it allows the end system to easily meet the worldwide energy reqirement.

Test conditions and notes10
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Line regulation is measured from low line to high line at rated load.
  5. 5. Load regulation is measured from 0% to 100% rated load.
  6. 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. 7. 3.3V,5V when the load factor 0~50%, the switching power less is reduced by burst operation, which will cause ripple and ripple noise to go beyond the specifications.
  8. 8. The ambient temperature derating of 5℃/1000m is needed for operating altitude greater than 2000m(6500ft).
  9. 9. 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. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)

FAQ

What types of 5V loads can the LRS-50-5 support at 10A?

At 5V and 10A (50W), the LRS-50-5 can power logic control boards, single-board computers, USB charging distribution bars, RS-485 communication modules, and indicator LED panels. The 10A current capacity supports several parallel 5V consumers simultaneously.

What is the operating temperature range of the LRS-50-5?

The LRS-50-5 operates from -30°C to +70°C. The -30°C lower limit allows cold-start in unheated enclosures and cold-storage environments. Operation toward +70°C requires output derating per the derating curve, which should be considered for warm industrial cabinet installations.

Does the LRS-50-5 carry certifications for both North American and European markets?

Yes. The LRS-50-5 is approved to UL62368-1 (North America) and TÜV BS EN/EN62368-1 (Europe), plus GB 4943.1 (China), BSMI CNS15598-1 (Taiwan), AS/NZS 60950.1 by CB (Australia/New Zealand), EAC TP TC 004 (Eurasia) and BIS (India).
