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 NSD15-48D 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 NSD15-12D12 for analog signal-conditioning circuits that need ±12V rails?

Yes, this model is suited to low-power analog and instrumentation circuits that require a ±12V constant-voltage output. Its 14.88W rating and 9.4-36V input range make it a reasonable fit for compact industrial and embedded signal-conditioning sections.

Is the NSD15-12D12 appropriate for data acquisition or measurement electronics inside industrial equipment?

It can be used where DAQ or measurement electronics need dual ±12V rails and the source voltage stays within 9.4-36V. The 14.88W capacity makes it better for control, sensing, and interface electronics than for heavier auxiliary loads.

Can this converter support bipolar power rails in an embedded test or automation system?

Yes, the dual ±12V output is intended for applications that need both positive and negative rails from one converter. That makes it relevant for embedded test fixtures, analog front ends, and automation electronics that are built around ±12V operation.

Is the NSD15-12D12 meant for outdoor cabinets or only protected indoor enclosures?

Its operating temperature range is -25°C to +70°C, which supports use across typical industrial enclosure conditions. No IP rating is listed in the provided specs, so it should not be treated as confirmed for exposed outdoor or washdown environments based on this data alone.

What are the main differences between the NSD15-12D12 and the other NSD15 family models?

The NSD15-D sheet lists six dual-output models. With 9.4~36VDC input: NSD15-12D5 at 15W, ±5V, 1.5A; NSD15-12D12 at 14.88W, ±12V, 0.62A; and NSD15-12D15 at 15W, ±15V, 0.5A. NSD15-48D5, NSD15-48D12 and NSD15-48D15 offer the same outputs with 18~72VDC input. The NSD15-12D12 is the 14.88W dual 12V option with 0.62A per rail.
