Test conditions and notes5
- 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. 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 )
- 5. 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 PS-05-48 for a low-power 48V industrial control circuit?
Yes, this unit provides constant-voltage 48V output for low-power control loads that stay within 5.28W and 0.11A. It is intended for light 48V electronics rather than equipment with higher startup or continuous current demand.
Is the PS-05-48 suitable for a small 48V telecom or IT module?
It can be suitable for a small 48V telecom or IT device if that load requires constant 48V and does not exceed 0.11A. With 5.28W available, it fits low-current electronics better than multi-module or higher-draw systems.
Would this work for a compact 48V embedded controller or monitoring device?
Yes, provided the controller or monitoring device is designed for 48V constant-voltage input and remains within 5.28W total draw. The 0.11A output limit makes it appropriate for very low-current embedded applications.
Can the PS-05-48 power a single 48V field device in an automation panel?
It can power a single low-power 48V field device when the device stays under 0.11A and 5.28W. That makes it better for small instrumentation or interface loads than for larger panel devices.
Can I use the PS-05-48 in outdoor or washdown conditions?
The specified operating range is -10°C to +60°C, but no IP rating is listed in the product data. Because of that, the published specs do not establish suitability for outdoor exposure, washdown, or other ingress-sensitive environments.
What are the differences between the PS-05-48 and the other PS-05 models?
In the PS-05 series, PS-05-5 is 5W at 5V and 1A, PS-05-12 is 5.4W at 12V and 0.45A, PS-05-15 is 5.25W at 15V and 0.35A, PS-05-24 is 5.28W at 24V and 0.22A, and PS-05-48 is 5.28W at 48V and 0.11A. The family keeps similar low-power form factors while changing output voltage and the corresponding available current.
