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-200D-48 to power 48V automation hardware from a 72-144VDC input source?
Yes, the listed specs show constant-voltage 48V output at up to 4.2A with a 72-144VDC input range. It is suitable for 48V automation hardware if the total load stays within 201.6W.
Is this model a good fit for 48V industrial control panels or communication equipment?
It can fit 48V control or communications equipment that needs steady constant-voltage power. The rated output is 48V and 4.2A, so the equipment load must remain at or below 201.6W.
Would the SD-200D-48 work for 48V embedded or mobile electronics on a high-voltage bus?
It is intended for systems with source input between 72-144VDC and provides constant-voltage 48V output. That makes it appropriate for 48V embedded or mobile electronics within the 4.2A output limit.
Is the SD-200D-48 suitable for outdoor installations?
The operating temperature is listed as -20°C to +60°C (refer to the derating curve), but no IP rating is provided in the specs. Without a stated IP rating, it should be used in protected enclosures rather than exposed outdoor locations.
How does the SD-200D-48 compare with related SD-200D converters?
The SD-200D models are 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. The family varies mainly by output voltage and current while staying near the 200W range.
