Test conditions and notes8
  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. Short circuit no more than 60 seconds.
  5. 5. 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 )
  6. 6. Derating to 80% load is needed for NSD15-48S series at 18Vdc input voltage. Full output wattage can be acquired when the input voltage is higher than 20Vdc.
  7. 7. EMC filter suggestion:
  8. 8. 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 NSD15-12S15 to power a 15V industrial control module from a wide-input system?

Yes, if the control module requires a constant 15V output and stays within 1A and 15W. This converter accepts 9.4~36V input and is designed for constant-voltage 15V output.

Is this DC-DC converter suitable for embedded electronics that need regulated 15V power?

It is suitable for embedded equipment that needs a constant 15V rail and does not exceed 1A or 15W. The 9.4~36V input range also makes it a fit for systems built around varying low-voltage input sources within that range.

Can I use this for a 15V automation sensor or interface circuit?

Yes, when the sensor or interface circuit is rated for constant 15V input and draws no more than 1A. Its 15W power rating and 9.4~36V input range fit low-power automation electronics that need a regulated 15V output.

Is the NSD15-12S15 suitable for outdoor or harsh-environment use?

The working temperature range is -25°C to +70°C (storage -40°C to +85°C), with load derating at higher ambient temperatures per the derating curve. No IP rating is listed and the converter is a component for installation in final equipment, so the published specs do not confirm suitability for direct outdoor exposure or washdown environments.

How does the NSD15-12S15 compare with other NSD15 series models?

The NSD15-S series offers 3.3V at 3.75A and 12.375W, 5V at 3A and 15W, 12V at 1.25A and 15W, and 15V at 1A and 15W. Each output comes in a 9.4~36VDC input version (NSD15-12S) and an 18~72VDC input version (NSD15-48S). The NSD15-12S15 is the 9.4~36VDC input, 15V, 1A, 15W single-output version.
