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 this converter for a 48V PLC, relay, and sensor circuit in automation equipment?

Yes, it can fit a 48V constant-voltage load when the source is within 19-36VDC. The output is rated at up to 4.2A and 201.6W, so the total PLC, relay, and sensor demand needs to stay inside that range.

Will this work for a 48V HMI or industrial touchscreen system?

It can support a 48V HMI or touchscreen system that expects constant-voltage power. This model provides 48V output up to 4.2A, with 201.6W total available power.

Is this suitable for a 48V embedded controller or communications device?

It is appropriate for 48V embedded or communications hardware if the equipment uses a fixed 48V input and the load does not exceed 4.2A or 201.6W. The 2:1 wide 19-36VDC input range also helps when the upstream source varies within that span.

Can this be used in a cold or hot indoor equipment enclosure?

The specified operating temperature range is -20°C to +60°C, with output derating per the derating curve, so it is intended to operate across a fairly wide enclosure temperature range. Because no IP rating is listed, the safer fit is a protected indoor enclosure rather than direct outdoor exposure.

What are the differences between the SD-200B-48 and the other SD-200B versions?

The SD-200B variants are SD-200B-5 at 170W, 5V, 34A; SD-200B-12 at 200.4W, 12V, 16.7A; SD-200B-24 at 201.6W, 24V, 8.4A; and SD-200B-48 at 201.6W, 48V, 4.2A. That means the selection is mainly about matching the required output voltage and current while staying within the same 19-36VDC input family.
