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-200B-12 for high-current 12V logic or controller loads from a 24V source?
Based on the spec sheet, this unit delivers constant-voltage 12V output at up to 16.7A from a 19-36VDC input range, so a 24V source is within range. That makes it suitable for higher-current 12V industrial or embedded loads up to 200.4W.
Is the SD-200B-12 appropriate for powering multiple 12V embedded devices on one rail?
It can be appropriate when the combined load remains within the listed 16.7A output current and 200.4W power rating. The 2:1 wide input range supports use on systems with 19-36VDC available upstream.
Would this model work for a 12V industrial computer or control backplane?
Yes, the specs support 12V applications, with constant-voltage 12V output and up to 16.7A available. The listed 1.5KVAC input-to-output isolation is also relevant for industrial equipment where isolation may be required.
How does SD-200B-12 compare with the other SD-200B models listed?
Based on the spec sheet, SD-200B-5 is 170W, 5V, 34A; SD-200B-12 is 200.4W, 12V, 16.7A; SD-200B-24 is 201.6W, 24V, 8.4A; and SD-200B-48 is 201.6W, 48V, 4.2A. The listed differences are output voltage, output current, and power across the SD-200B family.
Is the SD-200B-12 suitable for outdoor or temperature-variable enclosures?
The operating temperature range is specified as -20°C to +60°C with derating per the derating curve, which supports use across a defined industrial temperature range. The specs do not include an IP rating, so ingress protection for outdoor exposure is not defined in the product data.
