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 NSD10-48S9 to power a 9V embedded controller from a wide industrial DC bus?

Yes, this converter is suited to low-power embedded electronics that need a regulated 9V output from a 22-72V input range. Its 9.9W rating and 1.1A output current fit small controller, interface, and monitoring circuits rather than higher-draw loads.

Is the NSD10-48S9 a fit for 48V automation panels that need a separate 9V rail?

It can fit automation panels that distribute a 48V-class input within the stated 22-72V range and need a constant-voltage 9V output. With 9.9W available, it is better matched to auxiliary electronics, compact sensors, and low-power control sections than larger actuators.

Can this 9V converter be used for industrial sensing or monitoring modules?

It is appropriate for low-power sensing and monitoring modules that need a stable 9V rail and stay within 1.1A output current. The wide 22-72V input range also makes it practical where DC bus voltage can vary across different industrial or mobile systems.

Is the NSD10-48S9 suitable for outdoor or harsh-environment use?

The working temperature range is -25°C to +70°C, with storage from -40°C to +85°C, so the specs support operation across that span. However, no IP rating is listed, so the provided specs do not confirm protection against water or dust for exposed outdoor installation.

How does the NSD10-48S9 compare with the other NSD10 series options?

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; NSD10-48S5 at 10W, 5V, 2A; NSD10-48S12 at 9.96W, 12V, 0.83A; and NSD10-48S15 at 10.05W, 15V, 0.67A. The NSD10-48S9 itself is the 9.9W, 9V, 1.1A single-output option in that group.
