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 NSD10-12S5 for a 5V industrial controller or HMI support circuit?

Yes, it provides constant 5V output at up to 2A with a 10W power rating. It fits 5V control electronics, HMI support boards, and low-power automation devices when the total load remains within 5V, 2A, and 10W.

Is the NSD10-12S5 suitable for 5V USB-class or embedded peripherals inside equipment?

It can be used for 5V embedded peripherals and accessory circuits that need a regulated 5V rail. The sizing limit is 2A output current and 10W total power, so the connected 5V load needs to stay within those values.

Can this model power 5V sensors, interface boards, or compact automation modules?

Yes, the 5V constant-voltage output makes it suitable for 5V sensors, interface electronics, and compact automation modules. It is intended for lower-power 5V sections rather than loads above 2A or 10W.

Is the NSD10-12S5 appropriate where cabinet space is tight?

It is compact at 50.8 x 25.4 x 10.0 mm and weighs 0.02 kg, so it fits well in dense control layouts. That helps in embedded or industrial assemblies where a small 5V, 10W converter is needed.

Can the NSD10-12S5 handle indoor industrial temperature swings, and is it outdoor rated?

The working temperature range is -25C to +70C, with storage from -40C to +85C. The provided specs do not list an IP rating, so the product data does not describe it as sealed or outdoor rated by itself.

What are the main differences between the NSD10-12S5 and the other NSD10 variants?

In the 9.8~36V input branch, the series includes NSD10-12S3 at 8.25W, 3.3V, 2.5A; 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 22~72V input branch 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.
