Test conditions and notes5
- 1. All parameters NOT specially mentioned are measured at 12,24,48VDC 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 SD-25A-5 to power 5V embedded electronics or logic devices?
Yes, if the 5V electronics need constant-voltage power and the load stays within 5A and 25W. The listed input range for this model is 9.2-18VDC.
Is the SD-25A-5 suitable for a 5V industrial interface or communication module?
It can fit a 5V industrial interface or communication module that draws no more than 5A. The converter provides 25W output capacity.
Can this model support a compact 5V controller in an automation cabinet?
It is suitable for a compact 5V controller when the required output is constant voltage and the total load does not exceed 5A or 25W. The unit is specified for 9.2-18VDC input.
What are the main differences between the SD-25A output versions?
In the SD-25A range, SD-25A-5 is 25W at 5V and 5A, SD-25A-12 is 25.2W at 12V and 2.1A, and SD-25A-24 is 26.4W at 24V and 1.1A. All three share the same listed 9.2-18VDC input range.
Can the SD-25A-5 be used in outdoor equipment?
The published data lists an operating temperature range of -10°C to +60°C, with output derating at higher temperatures per the derating curve, but no IP rating is shown. That means the temperature limits are defined, while outdoor sealing or water resistance is not specified.
