Test conditions and notes5
  1. 1. All parameters NOT specially mentioned are measured at 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-350D-5 for a 5V industrial controller or logic system fed from a 72-144V DC source?

Yes, this model provides a constant 5V output and is rated for 60A up to 300W. It is suited to 5V control, logic, or embedded loads that stay within the 60A and 300W limits.

Is the SD-350D-5 a good fit for 5V embedded computing or industrial SBC loads?

It can be used where the equipment requires a regulated 5V supply and the total load remains at or below 300W. With 60A available at 5V, it fits higher-current 5V DC applications.

Can the SD-350D-5 power 5V automation electronics in a higher-voltage DC system?

Yes, it converts a 72-144V input to a constant 5V output, which is useful when a higher-voltage DC bus has to feed low-voltage automation electronics. Its rated output is 300W at 60A, so the downstream 5V load must stay within those limits.

Can this converter be used in outdoor equipment cabinets or unsealed locations?

The operating temperature range is specified as -20°C to +60°C, but no IP rating is listed in the provided specs. That supports temperature planning, but it does not confirm suitability for direct outdoor exposure or wet locations.

What are the main differences between the SD-350D-5 and the other SD-350D versions?

The SD-350D-5 is rated at 300W with 5V output and 60A, while the SD-350D-12 is 350.4W at 12V and 29.2A, the SD-350D-24 is 350.4W at 24V and 14.6A, and the SD-350D-48 is 350.4W at 48V and 7.3A. The family shares the same general format, but each version is sized for a different output voltage and current requirement.
