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-24 for 24V PLC or control-panel loads from a low-voltage DC source?
Yes, it delivers constant voltage 24V output from a listed 9-18V input range. Its output is rated for 4.2A and 100.8W, which suits moderate-power 24V DC loads.
Is the SD-100A-24 appropriate for 24V automation devices in mobile or battery-backed systems?
It can be used where the source stays within the listed 9-18V range and the load requires 24V DC. The converter is rated for up to 4.2A output current and 100.8W total output power.
Can this model support 24V embedded or industrial communication equipment?
Yes, it is intended for constant voltage 24V applications that stay within its 100.8W limit. The unit provides up to 4.2A, so it is better suited to lower-power 24V equipment than to heavier 24V loads.
Is the SD-100A-24 suitable for outdoor use or unconditioned indoor spaces?
The listed operating temperature range is -15°C to +60°C, which defines the environmental range in the specs. No IP rating is shown, so the product information does not describe it as weatherproof or outdoor-rated.
How does the SD-100A-24 compare with the other SD-100A versions?
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. They are all in the same product group, with the main difference being the output voltage and corresponding current.
