Test conditions and notes5
- 1. All parameters NOT specially mentioned are measured at 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-350C-5 for 5V industrial logic or processor boards that need high current?
Yes, this model delivers a constant 5V output up to 60A with a 300W power rating from a 36-72V input range. It is suited to 5V loads that need high current, provided the total draw stays within 60A and 300W.
Is the SD-350C-5 suitable for powering multiple 5V embedded devices from one converter?
It can support multiple 5V embedded loads on one rail because the output is regulated at 5V and rated for 60A total. System sizing should stay within the 300W maximum output power.
Can this converter be used for 5V backplanes, controller cards, or industrial computing hardware?
Yes, the 5V constant-voltage output is appropriate for 5V electronic loads where a 36-72V source is available. The available output capacity is 60A, with total power limited to 300W.
Is the SD-350C-5 meant for outdoor installations or only protected enclosures?
The operating temperature range is -20°C to +60°C, which defines the temperature conditions in the published specs. An IP rating is not listed, so protection against water and dust is unspecified and use in exposed outdoor conditions should not be assumed from the product data provided.
How does the SD-350C-5 compare with the other SD-350C models?
The SD-350C series shown here includes SD-350C-12 at 330W, 12V, 27.5A; SD-350C-24 at 350.4W, 24V, 14.6A; SD-350C-48 at 350.4W, 48V, 7.3A; and SD-350C-5 at 300W, 5V, 60A. This unit is the 5V version and has the highest listed output current of the four at 60A.
