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 NSD05-48S12 for a 12V sensor, relay, or interface module in a high-voltage control cabinet?

Yes, this converter is designed for applications that need a constant 12V output from an 18~72VDC input source. Its output is rated at 5.04W, so the connected 12V load must stay within that power limit.

Is the NSD05-48S12 suitable for 12V auxiliary power in industrial automation equipment?

It is suitable for low-power 12V auxiliary circuits that need regulated constant voltage and are supplied from an 18~72VDC source. The small 40.6 x 25.4 x 8.3 mm package helps when panel space is limited.

Can this model power a compact 12V control accessory inside embedded or OEM systems?

Yes, as long as the accessory is a 12V constant-voltage load and stays within the 5.04W output rating. The converter is also rated for operation from -25C to +70C, which suits many enclosed equipment environments.

Can the NSD05-48S12 be used in outdoor equipment cabinets?

The provided specs do not list an IP rating, so outdoor exposure resistance is not defined for this model. What is specified is an operating temperature range of -25C to +70C, so environmental protection would depend on the enclosure used around it.

What are the main differences between the NSD05-48S12 and the other NSD05 variants?

The 18~72VDC input versions are 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. The 9.2~36VDC input versions 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.
