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-15B-5 to power a small embedded controller from a 24V industrial supply?

Yes, this converter is suited to low-power embedded control hardware that needs a regulated 5V output from an 18-36VDC input source. It provides constant-voltage 5V output at up to 3A with a 15W power rating, which fits compact control electronics rather than higher-load devices.

Is the SD-15B-5 a fit for sensor interfaces or industrial communication boards that run on 5V?

It can be a fit when the load needs 5V constant-voltage power and stays within 3A and 15W. The 18-36VDC input range suits 24V-class systems, and the listed 1.5KVAC input-output withstand voltage is relevant in industrial and embedded environments.

Can this converter be used in automation panels for low-power 5V logic loads?

Yes, it is sized for low-power 5V logic loads in automation equipment when the source is within 18-36VDC. Its compact 78.0 × 51.0 × 28.0 mm housing and 0.18 kg weight also make it practical where panel space is limited.

How does the SD-15B-5 compare with the other SD-15B models?

Within the SD-15B group, SD-15B-5 is 15W, 5V, 3A; SD-15B-12 is 15W, 12V, 1.25A; and SD-15B-24 is 15W, 24V, 0.625A. The main differences are the output voltage and output current, while all three are part of the same 15W family.

Is the SD-15B-5 suitable for outdoor or harsh-environment use?

The listed operating temperature is -10°C to +60°C, with output derating at higher temperatures per the derating curve. The provided specs do not list an IP rating, so dust and water ingress protection are not specified in the product data.
