Test conditions and notes5
- 1. All parameters NOT specially mentioned are measured at 12,24,48,96VDC 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-100A-12 to run 12V industrial controls from a low-voltage DC source?
Yes, it provides a constant 12V output and accepts a listed 9-18V input range. Its 102W rating and 8.5A output make it suitable for moderate-power 12V DC loads.
Is the SD-100A-12 suitable for mobile or vehicle-based 12V electronics?
It is intended for applications that need 12V output from a source within the listed 9-18V range. With up to 8.5A output current, it fits 12V loads that stay within its 102W capacity.
Can this converter power 12V embedded systems or smaller automation devices?
Yes, the constant voltage 12V output is appropriate for embedded or automation equipment that requires regulated 12V DC. The available output is up to 8.5A, with a total power rating of 102W.
Is the SD-100A-12 meant for indoor use in colder or warmer environments?
The operating temperature range is listed as -15°C to +60°C. No IP rating is provided in the specs, so the product data does not identify it as an outdoor-rated enclosure.
How does the SD-100A-12 compare with the other SD-100A models?
In the SD-100A group, the SD-100A-5 is rated at 100W, 5V, 18A, the SD-100A-12 is rated at 102W, 12V, 8.5A, and the SD-100A-24 is rated at 100.8W, 24V, 4.2A. The main differences are output voltage and output current, while all are around the 100W class.
