Test conditions and notes8
- 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. Short circuit not more than 60 seconds.
- 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. To insure proper operation, a 220uF/100V electrolytic capacitor with Esr <1Ω must be added to the input line.
- 7. EMC filter suggestion:
- 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 NSD10-48S12 for a 12V PLC accessory or automation module?
It can suit compact PLC accessories or automation modules that need a constant 12V output from a 22-72VDC input source. The 9.96W rating makes it more appropriate for smaller 12V loads than for higher-power field equipment.
Is this a good fit for powering a 12V industrial communication or monitoring board?
Yes, if the board is designed for a regulated 12V supply and fits within the 9.96W output rating. Its 50.8 × 25.4 × 10.0 mm dimensions and 0.02 kg weight also make it practical for compact embedded or control enclosures.
Can the NSD10-48S12 be used in transportation or mobile equipment with wide input variation?
The wide 22-72VDC input range makes it relevant where the source can vary across a broad span but the load still needs constant 12V output. The working temperature range is -25°C to +70°C, so the installation must stay within it.
Is the NSD10-48S12 suitable for outdoor cabinets or unsealed equipment spaces?
No IP rating is provided in the supplied specs, so outdoor exposure or unsealed wet or dusty locations should not be assumed. What is stated is a -25°C to +70°C working temperature range, which addresses temperature only.
What are the main output options across the related NSD10 models?
The 9.8~36VDC input models on the NSD10-S sheet are NSD10-12S3 at 8.25W, 3.3V, 2.5A; NSD10-12S5 at 10W, 5V, 2A; NSD10-12S9 at 9.9W, 9V, 1.1A; NSD10-12S12 at 9.96W, 12V, 0.83A; and NSD10-12S15 at 10.05W, 15V, 0.67A. The 22~72VDC input variants listed alongside this model are NSD10-48S3 at 8.25W, 3.3V, 2.5A; NSD10-48S5 at 10W, 5V, 2A; NSD10-48S9 at 9.9W, 9V, 1.1A; and NSD10-48S15 at 10.05W, 15V, 0.67A.
