Test conditions and notes7
  1. 1. All parameters NOT specially mentioned are measured at 12, 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. 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 )
  5. 5. To insure proper operation, a 47uF/100V electrolytic capacitor with Esr <1Ω must be added to the input line.
  6. 6.EMC filter suggestion(TBD):
  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 NSD05-12S15 for a 15V analog or measurement circuit in industrial equipment?

It can fit low-power 15V analog or measurement circuits because it provides a constant 15V output at 4.95W. The 9.2~36V input range is also useful where the upstream supply can vary within that window.

Is this a good fit for embedded 15V support power inside automation hardware?

Yes, for low-power embedded 15V support rails, this model matches that use case with a regulated 15V constant-voltage output. Its 40.6 × 25.4 × 8.3 mm size and 0.007 kg weight help when board area and enclosure space are limited.

Can the NSD05-12S15 be used for low-power 15V interfaces in control cabinets?

It is appropriate for low-power 15V interface or support circuits that need a fixed 15V rail rather than a variable output. With 4.95W output capacity, it is better suited to lighter-duty electronics than to larger 15V loads.

What are the main differences between the NSD05-12S15 and the other NSD05 siblings?

Among the listed siblings, NSD05-12S3 is 3.96W at 3.3V and 1.2A, NSD05-12S5 is 5W at 5V and 1A, and NSD05-12S12 is 5.04W at 12V and 0.42A. The related 48-series models are NSD05-48S3 at 3.96W and 3.3V/1.2A, NSD05-48S5 at 5W and 5V/1A, NSD05-48S12 at 5.04W and 12V/0.42A, and NSD05-48S15 at 4.95W and 15V/0.33A.

Can this converter be used in cold or hot enclosed equipment spaces?

The specified operating temperature range is -25°C to +70°C, which supports use across a wide temperature span for enclosed equipment. The provided specs do not list an IP rating, so environmental sealing for outdoor exposure is not defined here.
