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-100A-5 for 5V embedded controllers or industrial computing hardware?

Yes, it provides a constant 5V output and can deliver up to 18A. With a 90W rating and a listed 9.5-18V input range, it fits higher-current 5V DC applications within that power limit.

Is the SD-100A-5 suitable for powering 5V logic or communications equipment from a low-voltage DC bus?

It is designed for 5V constant voltage output from an input source in the listed 9.5-18V range. The 18A output capacity supports 5V loads that need relatively high current within the 90W rating.

Can this converter be used for 5V automation electronics in battery-powered systems?

Yes, if the source remains within the specified 9.5-18V range and the load needs regulated 5V DC. The converter is rated for up to 90W total output power and 18A output current.

Is the SD-100A-5 intended for outdoor environments or only protected enclosures?

The operating temperature range is listed as -15°C to +60°C. No IP rating is provided, so the specs do not identify it as an outdoor-rated or water-resistant model.

How does the SD-100A-5 compare with the other SD-100A models?

Within the SD-100A family, the SD-100A-5 is 90W at 5V and 18A, the SD-100A-12 is 102W at 12V and 8.5A, and the SD-100A-24 is 100.8W at 24V and 4.2A. They are all around the same power class, with different output voltages and current levels.
