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-200D-12 to supply 12V industrial electronics from a 72-144VDC source?

Yes, the listed specs show constant-voltage 12V output at up to 16.7A with input from 72-144VDC. It is appropriate for 12V equipment when the total load stays within the 200.4W rating.

Is this model suitable for 12V PLC accessories, logic boards, or embedded controllers?

It can fit 12V control electronics that need higher current from a constant-voltage source. The rated output is 12V and 16.7A, so it works best where the connected devices collectively remain within 200.4W.

Would the SD-200D-12 work for 12V automation or test equipment on a higher-voltage bus?

It is designed for systems with a 72-144VDC input range and a 12V constant-voltage output. That makes it a practical option for 12V automation or bench electronics on higher-voltage input systems, as long as demand does not exceed 16.7A.

Is the SD-200D-12 intended for indoor use only?

The operating temperature is listed as -20°C to +60°C (refer to the derating curve), which covers a broad industrial temperature range. However, no IP rating is given, so it should be considered a unit for protected indoor cabinets or enclosed equipment rather than open outdoor exposure.

How does the SD-200D-12 compare with other SD-200D models?

The SD-200D family is SD-200D-5 at 200W, 5V, 40A; SD-200D-12 at 200.4W, 12V, 16.7A; SD-200D-24 at 201.6W, 24V, 8.4A; and SD-200D-48 at 201.6W, 48V, 4.2A. They share the same series but differ in output voltage, output current, and rated wattage values.
