Test conditions and notes5
- 1. All parameters NOT specially mentioned are measured at 12,24,48VDC 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 0.1uf & 47uf 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 http://www.meanwell.com)
- 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-25C-5 to power 5V industrial logic or embedded electronics from a 36-72V source?
Yes, it provides 5V constant voltage output with up to 5A and 25W available. That makes it suitable for compact 5V control electronics, embedded boards, and similar low-voltage loads when the source is within 36-72V.
Is the SD-25C-5 appropriate for 5V communication modules or monitoring hardware in an automation cabinet?
It can fit those types of applications if the total output demand stays within 5A and 25W. The regulated 5V output is intended for low-power electronics, not larger 5V systems that need more than 25W.
Can this converter be used in telecom or industrial control systems that need a small 5V rail?
It is designed for systems with input voltage in the 36-72V range that need a 5V constant-voltage output. With 25W total output capacity, it suits modest 5V auxiliary electronics and embedded devices.
How does the SD-25C-5 compare with the other SD-25C output options?
In the SD-25C range, SD-25C-5 is rated at 25W, 5V, 5A; SD-25C-12 is 25.2W, 12V, 2.1A; and SD-25C-24 is 26.4W, 24V, 1.1A. All three use the same 36-72V input range and differ by output voltage, current, and wattage.
Is the SD-25C-5 suitable for outdoor equipment or harsh washdown areas?
No IP rating is listed in the available specs, so the published data does not indicate outdoor or washdown suitability. The operating temperature range is -10°C to +60°C, which supports use in enclosed or otherwise protected equipment environments within that range.
