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-100B-5 to power 5V industrial controllers or embedded electronics from a 19-36V source?
Yes, this model delivers 5V constant voltage output up to 20A with a 100W rating. It is appropriate for 5V embedded or control electronics when the source feeding the converter stays within 19-36V.
Is the SD-100B-5 suitable for 5V logic-heavy systems with higher current demand?
It is better suited to 5V applications that need more current than the 12V or 24V versions because this model is rated for 20A at 5V. The output remains constant voltage, which is typical for digital and embedded loads that expect a fixed 5V rail.
Can the SD-100B-5 be used for 5V automation interfaces, industrial computing boards, or communications modules?
It can fit 5V industrial and embedded subsystems that need regulated output and stay within 20A and 100W. That makes it a practical choice for denser 5V electronics loads than models intended for 12V or 24V outputs.
Is the SD-100B-5 intended for outdoor environments?
The stated operating temperature range is -10°C to +60°C, but no IP rating is listed in the provided specs. On that basis, outdoor or exposed-environment suitability is not defined, so it is best considered for protected indoor enclosures within the stated temperature range.
How does the SD-100B-5 compare with the other SD-100 output variants?
The 5V SD-100 models SD-100A-5, SD-100B-5, SD-100C-5, and SD-100D-5 are rated at 100W and 20A. The 12V versions SD-100A-12, SD-100B-12, SD-100C-12, and SD-100D-12 are 102W and 8.5A, while the 24V versions SD-100A-24, SD-100B-24, SD-100C-24, and SD-100D-24 are 100.8W and 4.2A.
