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 NSD15-12D5 for logic and analog circuits that need ±5V rails?

Yes, this converter fits low-power electronics that need a dual ±5V constant-voltage supply from a 9.4-36V input range. Its 15W rating and 1.5A output current suit compact embedded, control, and interface circuits rather than larger loads.

Is the NSD15-12D5 a good fit for industrial data and communication boards using split 5V rails?

It can be used where a board or subsystem needs both positive and negative 5V rails and the available source is within 9.4-36V. That makes it relevant for low-power industrial communication, interface, and processing electronics built around ±5V operation.

Can this converter power a bipolar 5V rail for embedded test equipment?

Yes, the ±5V output is suited to embedded test or measurement electronics that need a split low-voltage supply. With 15W available, it is sized for auxiliary electronics and signal sections, not for high-draw devices.

Is the NSD15-12D5 intended for outdoor use?

The specified operating range is -25°C to +70°C, which supports many protected industrial environments. No IP rating is listed, so the provided specs do not establish suitability for direct outdoor exposure or wet locations.

How does the NSD15-12D5 compare with the other NSD15 converters?

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. With 18~72VDC input: NSD15-48D5, NSD15-48D12 and NSD15-48D15 with the same outputs. The NSD15-12D5 is the dual 5V model with 15W output and 1.5A per rail.
