Test conditions and notes7
  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. 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 )
  5. 5. To insure proper operation, a 47uF/100V electrolytic capacitor with Esr <1Ω must be added to the input line.
  6. 6.EMC filter suggestion(TBD):
  7. 7. 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 NSD05-48S15 to supply a 15V analog or signal-conditioning circuit in industrial equipment?

Yes, this model provides a constant 15V output and is intended for low-power loads within its 4.95W rating. It is a practical choice when the available source falls within the listed 18~72VDC input range.

Is the NSD05-48S15 suitable for compact 15V electronics inside automation or test systems?

It can be used for compact 15V electronics that need regulated constant voltage and stay within the specified output capability. Its dimensions are 40.6 x 25.4 x 8.3 mm, which helps in dense control or test assemblies.

Can this converter power a small 15V module in an embedded OEM enclosure?

Yes, provided the module requires a constant 15V supply and does not exceed the unit's 4.95W output rating. The operating temperature range of -25C to +70C supports use in enclosed equipment operating within that range.

Is the NSD05-48S15 rated for outdoor or exposed industrial environments?

No IP rating is shown in the provided specifications, so exposed outdoor suitability is not defined. The environmental data provided includes the -25C to +70C operating temperature range and 0~95% RH working humidity.

How does the NSD05-48S15 differ from other converters in the same series?

For 18~72VDC input, the series includes NSD05-48S3 at 3.96W, 3.3V, 1.2A; NSD05-48S5 at 5W, 5V, 1A; NSD05-48S12 at 5.04W, 12V, 0.42A; and NSD05-48S15 at 4.95W, 15V, 0.33A. For 9.2~36VDC input, the matching models are NSD05-12S3 at 3.96W, 3.3V, 1.2A; NSD05-12S5 at 5W, 5V, 1A; NSD05-12S12 at 5.04W, 12V, 0.42A; and NSD05-12S15 at 4.95W, 15V, 0.33A.
