Test conditions and notes5
  1. 1. All parameters NOT specially mentioned are measured at 12,24,48,96VDC 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-100D-5 to power 5V embedded controllers from a 72-144V DC source?

Yes. This unit converts 72-144V input to regulated 5V constant-voltage output. Its 100W rating and 20A output current make it suitable for higher-current 5V embedded and control electronics on high-voltage DC systems.

Is the SD-100D-5 suitable for 5V industrial computers or data acquisition hardware?

It is a fit when the equipment requires 5V input and the total load stays within 100W or 20A. The wide 72-144V input range is useful in systems built around higher-voltage DC buses. Its constant-voltage output is intended for electronics that need a stable 5V supply.

Can this model power several 5V automation devices from one high-voltage DC bus?

It can support multiple 5V devices if their combined demand remains at or below 100W and 20A. That makes it practical for grouped 5V control, monitoring, or processing electronics fed from a 72-144V source. It is better suited to moderate-power 5V loads than the smaller 15W or 25W units in the same series.

Can the SD-100D-5 be used in outdoor equipment enclosures?

No IP rating is listed for this converter, so it is generally better for protected indoor enclosures than direct outdoor exposure. The operating temperature range is -10°C to +60°C. If it is placed in outdoor equipment, the surrounding enclosure would need to provide the environmental protection.

What distinguishes the SD-100D-5 from the other SD-100D models?

The difference is the output class within the same family. SD-100D-5 is 100W at 5V and 20A, SD-100D-12 is 102W at 12V and 8.5A, and SD-100D-24 is 100.8W at 24V and 4.2A. All three stay near the 100W range while targeting different output voltages and current levels.
