Product Code : LRS-50 Series
Product Description

We have gained the market expertise and experience to supply and trade an extensive range of 50W Single Output Switching Power Supply. It contains top notch integrated circuits, resistor, transistor and other such components. Therefore, the offered power supplier can deliver uninterrupted output for the prolong duration. 50W Single Output Switching Power Supply is packed in special damage free packaging material in order to ensure its tamper free transportation. 

LRS-50 series is a 50W 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 90%, the design of metallic mesh case enhances the heat dissipation 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 requirement. LRS-50 has the complete protection functions and 5G anti- vibration 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-50 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℃ of ambient temperature.
  • Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 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 load.
  • 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.
  • 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.
  • The ambient temperature derating of 5℃/1000m is needed for operating altitude greater than 2000m(6500ft).
  • 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."
