Test conditions and notes7
- 1. All parameters NOT specially mentioned are measured at 12, 48VDC input, rated load and 25℃ of ambient temperature.
- 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. Tolerance : includes set up tolerance, line regulation and load regulation.
- 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. To insure proper operation, a 47uF/100V electrolytic capacitor with Esr <1Ω must be added to the input line.
- 6.EMC filter suggestion(TBD):
- 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 NSD05-12S5 to power a 5V microcontroller or embedded control board in an industrial panel?
Yes, this model provides a constant 5V output at up to 1A, with 5W total output power. It is suited to low-power embedded boards, control logic, and small industrial electronics when the available source is within the listed 9.2~36VDC input range.
Is the NSD05-12S5 a good fit for powering small 5V monitoring or communication modules in automation equipment?
It can be a fit for small 5V modules that need constant voltage and stay within the 1A, 5W output limit. The compact 40.6 x 25.4 x 8.3 mm size also suits space-constrained automation assemblies.
Can this converter be used for low-power 5V electronics inside OEM machinery?
Yes, if the electronics need a regulated 5V supply and draw no more than 1A. Its operating temperature range of -25C to +70C supports use inside many industrial enclosures where conditions stay within that range.
Is the NSD05-12S5 intended for outdoor or washdown environments?
No IP rating is listed for this model, so outdoor or washdown suitability is not stated in the provided specs. The environmental limits given are an operating temperature range of -25C to +70C and 0~95% RH working humidity, so use a suitable enclosure if exposure is a concern.
How does the NSD05-12S5 compare with the other NSD05 series options?
Within the 9.2~36VDC input group, the series includes 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. The 18~72VDC input group 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.
