Test conditions and notes8
  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. Short circuit not more than 60 seconds.
  5. 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. 6. To insure proper operation, a 220uF/100V electrolytic capacitor with Esr <1Ω must be added to the input line.
  7. 7. EMC filter suggestion:
  8. 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 NSD10-48S3 for a 3.3V embedded controller or processor board?

Yes, this model is well aligned with embedded controller, processor, or communications boards that need constant 3.3V output. Its 8.25W rating and 2.5A output spec make it a stronger fit for 3.3V logic-centric loads than the higher-voltage versions.

Is the NSD10-48S3 suitable for industrial IoT or edge computing electronics?

It can fit compact industrial IoT or edge electronics that are designed around a regulated 3.3V rail and a 22-72VDC input source. The small 50.8 × 25.4 × 10.0 mm form factor is useful where electronics density matters.

Can this converter power 3.3V communication or automation boards inside control equipment?

It is suitable for low-power 3.3V communication, monitoring, or automation boards when the total load stays within 8.25W. The wide input range and constant-voltage output are consistent with control-system subassemblies rather than larger end loads.

Does the NSD10-48S3 work in harsh temperature conditions?

The specified working temperature range is -25°C to +70°C, with storage rated from -40°C to +85°C and humidity up to 95% RH. No IP rating is listed, so temperature capability should not be read as outdoor sealing or moisture protection.

What other NSD10 output versions are available alongside the NSD10-48S3?

On the NSD10-S spec sheet, the 9.8~36VDC input versions 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 other 22~72VDC input versions are NSD10-48S5 at 10W, 5V, 2A; NSD10-48S9 at 9.9W, 9V, 1.1A; NSD10-48S12 at 9.96W, 12V, 0.83A; and NSD10-48S15 at 10.05W, 15V, 0.67A. All share the same 50.8 × 25.4 × 10 mm package and -25°C to +70°C working temperature.
