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 NSD10-48S5 for 5V industrial control or embedded computing hardware?
Yes, it can fit compact industrial control or embedded computing hardware that needs a constant 5V output from a 22-72VDC input source. With a 10W rating and 2A output, it suits compact 5V logic and control loads within those limits.
Is the NSD10-48S5 suitable for 5V gateways, HMI logic boards, or monitoring devices?
It is a practical option for 5V gateways, HMI logic sections, and monitoring electronics if the load stays within 10W. The 50.8 × 25.4 × 10.0 mm size also helps in compact automation assemblies.
Can this model be used for low-power 5V automation electronics in a wide-temperature enclosure?
Yes, if the electronics need a regulated 5V output and the source is within 22-72VDC. Its working temperature range is -25°C to +70°C, so the enclosure temperature must stay inside that range.
Is the NSD10-48S5 suitable for outdoor installations?
An IP rating is not provided in the supplied specs, so exposed outdoor use is not established here. The listed environmental data is the -25°C to +70°C working temperature range and up to 95% RH humidity, which covers temperature but not ingress protection.
How does the NSD10-48S5 differ from the other NSD10 models in the same series?
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 NSD10-48S3 at 8.25W, 3.3V, 2.5A; 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.
