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-100D-12 to power a 12V PLC or HMI from a 72-144V DC source?
Yes. This converter accepts 72-144V input and delivers regulated 12V constant-voltage output. Its 102W, 8.5A rating suits many 12V PLC, HMI, and panel-control loads on high-voltage DC systems.
Is the SD-100D-12 appropriate for 12V communication or monitoring equipment in industrial cabinets?
It is intended for 12V electronics that need stable constant-voltage power from a 72-144V source. The 8.5A output current and 102W capacity make it suitable for moderate-power communication, monitoring, and control devices. The 2:1 input range helps when the upstream DC bus varies within that 72-144V window.
Can this model support 12V embedded or automation devices on a 96V or 110V DC bus?
It is designed for high-voltage DC inputs within 72-144V, so it fits systems built around that bus range. On the output side, it provides 12V at up to 8.5A with a total power limit of 102W. That makes it a practical match for 12V embedded controllers and automation electronics that stay within those limits.
Is the SD-100D-12 meant for indoor or outdoor use?
It is designed for indoor use. The operating temperature range is -10°C to +60°C. For outdoor cabinets, additional environmental protection would normally be required.
What is the main difference between the SD-100D-12 and the other SD-100D versions?
The SD-100D family shares the same high-voltage input class, but the outputs differ. SD-100D-12 is 102W at 12V and 8.5A, SD-100D-24 is 100.8W at 24V and 4.2A, and SD-100D-5 is 100W at 5V and 18A. That means the choice within this group is mainly output voltage and available current at roughly the same 100W class.
