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 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-50 series serves as a high price-toperformance power supply solution for various industrial applications. ■ Model Encoding LRS - 50 - 3.3 Output voltage Output wattage Series name File Name:LRS-50-SPEC 2015-12-31 LRS-50 50W Single Output Switching Power Supply series SPECIFICATION MODEL OUTPUT INPUT LRS-50-3.3 LRS-50-5 LRS-50-12 LRS-50-15 LRS-50-24 LRS-50-36 LRS-50-48 DC VOLTAGE 3.3V 5V 12V 15V 24V 36V 48V RATED CURRENT 10A 10A 4.2A 3.4A 2.2A 1.45A 1.1A CURRENT RANGE 0 ~ 10A 0 ~ 10A 0 ~ 4.2A 0 ~ 3.4A 0 ~ 2.2A 0 ~ 1.45A 0 ~ 1.1A RATED POWER 33W 50W 50.4W 51W 52.8W 52.2W 52.8W RIPPLE & NOISE (max.)

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. 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. The ambient temperature derating of 5℃/1000m is needed for operating altitude greater than 2000m(6500ft). 9. The power supply is considered a component which will be installed into a final equipment. 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.
