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 NSD10-12S9 for 9V control electronics or monitoring equipment?
Yes, it delivers constant 9V output at up to 1.1A with a 9.9W rating. It suits 9V control, monitoring, and embedded support electronics that stay within 9V, 1.1A, and 9.9W.
Is this converter suitable for 9V instrumentation or compact industrial interface circuits?
It can be used for 9V instrumentation and interface circuits when those loads require a regulated constant-voltage output. The output capacity is limited to 1.1A and 9.9W, so it is meant for smaller 9V loads.
Can the NSD10-12S9 power a 9V embedded module inside automation equipment?
It is appropriate for a 9V embedded module, alarm board, or low-power communications circuit if the module needs a constant 9V supply. The load must fit within the converter's 1.1A output current and 9.9W power rating.
Does the small size of the NSD10-12S9 make it practical for compact equipment designs?
Yes, the body size is 50.8 x 25.4 x 10.0 mm and the weight is 0.02 kg, which is useful in compact control and embedded layouts. It is intended for designs that need a small 9V converter with up to 9.9W output.
Is the NSD10-12S9 suitable for outdoor enclosures or only protected locations?
The working temperature range is -25C to +70C, with storage from -40C to +85C. However, no IP rating appears in the provided specs, so the product data supports use in protected environments rather than claiming direct outdoor exposure capability.
How does the NSD10-12S9 fit into the NSD10 family lineup?
For 9.8~36V input models, the sibling options are NSD10-12S3 at 8.25W, 3.3V, 2.5A; NSD10-12S5 at 10W, 5V, 2A; NSD10-12S12 at 9.96W, 12V, 0.83A; and NSD10-12S15 at 10.05W, 15V, 0.67A. The 22~72V input family includes NSD10-48S3 at 8.25W, 3.3V, 2.5A; 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 x 25.4 x 10 mm package and -25C to +70C working temperature.
