Test conditions and notes5
  1. 1. All parameters NOT specially mentioned are measured at normal input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 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. 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-15A-5 to power a 5V embedded controller or industrial interface board from a 9.2-18VDC input source?

Yes, this converter provides constant 5V output at up to 3A with a total 15W rating. That makes it suitable for low-power 5V embedded controllers, interface boards, or similar electronics within those output limits.

Is the SD-15A-5 suitable for a 5V logic or communications module in an automation cabinet?

It is intended for regulated 5V loads that need no more than 3A. With a 9.2-18VDC input range and compact 78.0 × 51.0 × 28.0 mm size, it fits small automation or control electronics rather than larger 5V systems.

Can this converter run a small 5V industrial computing or monitoring device?

It can support a low-power 5V device as long as the total load stays within 15W and 3A. The constant voltage output is better suited to stable 5V electronics than to loads that require a different output type.

Can the SD-15A-5 be used in hot or cold industrial conditions?

The rated operating temperature range is -10°C to +60°C, with output derating at higher temperatures per the derating curve. No IP rating is shown in the provided specs, so the listing does not define outdoor or water-exposed suitability.

What are the differences between the SD-15A-5 and the other SD-15A versions?

In the SD-15A range, SD-15A-5 is 15W, 5V, 3A; SD-15A-12 is 15W, 12V, 1.25A; and SD-15A-24 is 15W, 24V, 0.625A. All three use the same 9.2-18VDC input range, constant voltage operation, -10°C to +60°C operating temperature (with derating), 78 × 51 × 28 mm dimensions, 0.18 kg weight, and EAC TP TC 004 approval.
