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-200C-48 to run a 48V industrial controller from a 36-72VDC bus system?

Yes, the listed specs show constant-voltage 48V output at up to 4.2A with a 36-72VDC input range. That makes it suitable when your source falls within 36-72VDC and the controller load stays within 201.6W.

Is this converter suitable for 48V automation sensors and I/O modules on mobile or embedded equipment?

It can fit 48V automation loads that need stable constant-voltage output rather than variable current drive. The rated output is 48V and 4.2A, so the combined load should remain within 201.6W.

Can the SD-200C-48 power a 48V HMI or communication panel in an industrial cabinet?

It is designed for constant-voltage output, so it can support 48V HMI or panel electronics when the total draw is within 4.2A. The 2:1 wide 36-72VDC input range also gives flexibility for systems operating across that span.

Is the SD-200C-48 appropriate for indoor or outdoor environments?

The specs list an operating temperature of -20°C to +60°C (refer to the derating curve), but no IP rating is stated. Without an IP rating, it should be treated as a converter for protected indoor enclosures rather than exposed outdoor use.

How does the SD-200C-48 compare with the other SD-200C models?

Within the SD-200C group, SD-200C-5 is listed at 200W, 5V, 40A; SD-200C-12 at 200.4W, 12V, 16.7A; SD-200C-24 at 201.6W, 24V, 8.4A; and SD-200C-48 at 201.6W, 48V, 4.2A. All are part of the same series family, but the output voltage, current, and wattage values differ by model.
