Test conditions and notes6
- 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 0.1μF & 47μF parallel capacitor.
- 3. Tolerance : includes set up tolerance, line regulation and load regulation.
- 4. 33.3% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
- 5. 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 )
- 6. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ
Can I use the LPS-50-48 for 48V industrial controls, telecom accessories, or network hardware?
Yes, if the equipment requires constant voltage 48V DC and the load stays within 52.8W and 1.1A. It is best matched to lighter 48V devices rather than higher-current 48V loads.
Is the LPS-50-48 suitable for compact embedded equipment or slim control cabinets?
It is built in a compact format at 195.0 x 55.0 x 23.0 mm and weighs 0.24 kg. The 23.0 mm profile helps where enclosure height is limited.
Can this power supply run 48V sensors, transmitters, or automation modules?
It can power 48V constant voltage devices up to 1.1A total output current. Buyers should check that the complete connected load remains within 52.8W.
Would the LPS-50-48 fit low-power 48V DC systems used in industrial or IT equipment?
It is a fit for low-power 48V applications that need a regulated output and accept up to 1.1A available current. The universal 90-264VAC input also supports operation from common AC input ranges.
Is the LPS-50-48 rated for outdoor exposure?
The product data specifies operation from -20°C to +70°C, with output derating at higher ambient temperatures, but no IP rating is listed. Based on the provided specs, temperature range is defined while outdoor ingress protection is not specified.
