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 NSD15-48D5 to power a 5V PLC interface or industrial control board?

It can fit industrial control electronics that need regulated ±5V rails and stay within 1.5A per output. The unit is rated for 15W total, so it is best suited to lower-power PLC interface, logic, or monitoring boards rather than larger 5V loads.

Is this converter suitable for embedded 5V devices inside a wide-input automation cabinet?

Yes, if the embedded device needs regulated ±5V rails and the source matches the listed 18-72VDC input range (full output above 20VDC; derate to 80% load at 18VDC). Its compact 50.8 × 38.1 × 9.82 mm size also makes it easier to place in space-constrained control assemblies.

Can I use this model for 5V industrial sensors or data-acquisition modules?

It is a dual ±5V constant-voltage model with up to 1.5A per output, so it can support 5V sensors or DAQ modules that stay within that current budget. Buyers should size the total connected load against the 15W rating rather than treating it as a higher-current 5V supply.

Would the NSD15-48D5 work for small 5V IT or communications electronics in equipment enclosures?

It can be used for compact 5V electronics such as low-power communications or monitoring hardware when the load remains within ±5V, 1.5A per output, and 15W. The listed UL62368-1 and EAC TP TC 004 approvals may also matter for equipment builders working to documented compliance requirements.

Is the NSD15-48D5 intended for outdoor use or harsh exposed environments?

The provided specs list an operating temperature range of -25°C to +70°C, but they do not include an IP rating. That means the product data supports temperature suitability only, not outdoor or washdown protection claims, so it is generally evaluated as an enclosed indoor component unless the overall system enclosure provides that protection.

How does the NSD15-48D5 compare with other NSD15 48-input series models?

Within the 18~72VDC-input models on this sheet, NSD15-48D5 is 15W with ±5V output at 1.5A. The other options are NSD15-48D12 at 14.88W with ±12V at 0.62A, and NSD15-48D15 at 15W with ±15V at 0.5A.
