Test conditions and notes7
  1. 1. All parameters NOT specially mentioned are measured at 12,24,48VDC 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. Short circuit not more than 60 second.
  5. 5. DC source wires ≧5cm, an input external al capacitor 47 ~ 100uF is required.
  6. 6. 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 230mm*230mm 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 )
  7. 7. 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 SDM30-48S15 to derive 15V power for industrial instrumentation from a 36~72V source?

Yes, this converter is intended for a 36~72V input range and delivers a constant 15V output. With a 30W rating and 2A output current, it fits lower-power 15V instrumentation or control circuits that need regulated voltage. The compact 50.8 × 50.8 × 16.0 mm body also helps in tight equipment layouts.

Is the SDM30-48S15 appropriate for embedded or automation equipment that runs on 15V?

It is appropriate where the upstream source falls within 36~72V and the downstream equipment requires constant 15V. The available output is 2A with a 30W limit, so it is best for moderate 15V loads rather than higher-demand devices. That makes it relevant for embedded subsystems, interface boards, and compact automation assemblies.

Can this model be used in a 48V panel to power 15V analog or control sections?

Yes, a 48V nominal source falls inside the 36~72V input range. The unit provides regulated 15V output at up to 2A, which suits smaller analog and control sections that are designed around 15V rails. Its constant-voltage mode is the right type of output for electronics expecting stable 15V input.

How does the SDM30-48S15 compare with the other 36~72V input SDM30 versions?

In the 36~72V input branch, the SDM30-48S3 is 16.5W at 3.3V and 5A, the SDM30-48S5 is 25W at 5V and 5A, the SDM30-48S12 is 30W at 12V and 2.5A, and this SDM30-48S15 is 30W at 15V and 2A. The series also includes 12V-input models at 16.5W, 25W, 25.2W, and 25.5W, plus 24V-input models at 16.5W, 25W, 30W, and 30W depending on output voltage. Selection is mainly a matter of matching the input range and the required output voltage, current, and wattage.

Can the SDM30-48S15 be used in hot or cold industrial environments?

The stated operating temperature range is -25°C to +85°C, so it is designed for a broad temperature window. The specs shown do not include an IP rating, which means the temperature range should not be read as proof of outdoor exposure resistance. It is better suited to protected equipment housings where environmental sealing is handled by the enclosure.
