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-12 to power a 12V industrial sensor or small control accessory from a 9.2-18VDC input source?

Yes, this model is a constant voltage DC-DC converter with a 12V output and 1.25A output current. Its 15W rating and 9.2-18VDC input range fit low-power 12V industrial sensors, control accessories, or embedded devices that stay within those limits.

Is the SD-15A-12 suitable for a compact embedded 12V electronics load in a mobile or battery-based system?

It can be a fit when your source stays within the 9.2-18VDC input range and the load needs regulated 12V constant voltage output. With 15W available in a 78.0 × 51.0 × 28.0 mm package, it is aimed at compact low-power 12V loads rather than higher-current equipment.

Can this converter support a low-power 12V automation device in a control enclosure?

This unit is intended for low-power 12V automation or control devices that draw no more than 1.25A at 12V. The 15W output rating and 1.5KVAC input-output withstand voltage make it more appropriate for small auxiliary loads than for larger 12V control hardware.

Is the SD-15A-12 rated for outdoor or harsh-temperature use?

The operating temperature range is -10°C to +60°C, with output derating at higher temperatures per the derating curve. No IP rating is listed in the provided specs, so outdoor exposure or washdown suitability is not specified by this product data.

What is the difference between the SD-15A-12 and the other SD-15A models?

Within the SD-15A group, 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 share the 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.
