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 NSD05-12S12 in a 12V industrial control panel?

It is a constant-voltage DC-DC converter with a 12V output and 5.04W power, which fits low-power 12V control electronics. The 9.2~36V input range also suits systems that need to accept a wide DC supply window in industrial and automation equipment.

Is this converter suitable for embedded 12V auxiliary circuits inside automation equipment?

Yes, it is sized for low-power 12V auxiliary rails where a constant 12V output is required. Its compact 40.6 × 25.4 × 8.3 mm package and 0.007 kg weight make it easier to place in dense embedded or control assemblies.

Can this model be used for low-power 12V instrumentation or sensor power in a machine enclosure?

This model can fit low-power 12V instrumentation loads because it provides a regulated 12V constant-voltage output at 5.04W. It is better aligned with small electronics and interface circuits than with higher-power 12V loads.

How does the NSD05-12S12 compare with the other NSD05 series output options?

In the listed sibling range, NSD05-12S3 is 3.96W at 3.3V and 1.2A, NSD05-12S5 is 5W at 5V and 1A, and NSD05-12S15 is 4.95W at 15V and 0.33A. The related 48-series siblings are NSD05-48S3 at 3.96W and 3.3V/1.2A, NSD05-48S5 at 5W and 5V/1A, NSD05-48S12 at 5.04W and 12V/0.42A, and NSD05-48S15 at 4.95W and 15V/0.33A.

Is the NSD05-12S12 suitable for outdoor or harsh-environment use?

The published specs show an operating temperature range of -25°C to +70°C, so the temperature range supports use in a broad indoor equipment environment. No IP rating is listed in the provided specs, so outdoor exposure or washdown suitability is not specified by this data.
