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 NSD15-12D15 for analog amplifiers or interface boards that require ±15V?

Yes, this converter is a fit for low-power analog electronics that need a ±15V constant-voltage supply. Its 15W rating and 9.4-36V input range align with compact industrial, embedded, and instrumentation circuits built around ±15V rails.

Is the NSD15-12D15 suitable for transducer and signal-processing modules in control equipment?

It can be used for signal-processing and transducer support circuits where dual ±15V rails are required and the source stays within 9.4-36V. The 15W power level is appropriate for electronics sections, not high-power field devices.

Can this model power a bipolar supply rail in industrial test and measurement equipment?

Yes, the ±15V output is relevant for measurement and test assemblies that use both positive and negative rails. With 15W available, it fits compact analog subsystems, conditioning stages, and embedded measurement boards.

Does the NSD15-12D15 support outdoor use in exposed areas?

The converter is rated for -25°C to +70°C operation, so its temperature spec covers a broad indoor industrial range. Since no IP rating is provided, the listed data does not confirm it for exposed outdoor environments where dust or water protection is required.

How does the NSD15-12D15 differ from the other NSD15 models in the same family?

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 NSD15-12D15 is the 15W dual 15V version with 0.5A per rail.
