Test conditions and notes7
  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. 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 )
  5. 5. To insure proper operation, a 47uF/100V electrolytic capacitor with Esr <1Ω must be added to the input line.
  6. 6.EMC filter suggestion(TBD):
  7. 7. 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 NSD05-48S5 to power a 5V controller or HMI accessory in industrial equipment?

Yes, it is suitable for low-power 5V electronics that need a constant-voltage supply and stay within the 1A, 5W output rating. It accepts an 18~72VDC input, which makes it useful where the source is in that range.

Is the NSD05-48S5 a fit for 5V communication or monitoring modules in automation panels?

It can be a fit for compact 5V monitoring, communication, or interface modules that do not exceed 1A. The unit's small 40.6 x 25.4 x 8.3 mm form factor also helps in crowded panel layouts.

Can this converter be used for embedded 5V electronics in OEM machinery?

Yes, provided the embedded electronics require a constant 5V supply and remain within the 5W output limit. Its operating range of -25C to +70C supports use inside machinery enclosures operating within those temperatures.

Is the NSD05-48S5 suitable for outdoor control boxes or exposed locations?

The provided specifications do not include an IP rating, so exposed outdoor use is not defined. The environmental data listed covers the -25C to +70C operating temperature range and 0~95% RH working humidity, so enclosure protection would need to be considered separately.

How does the NSD05-48S5 compare with the rest of the NSD05 range?

For 18~72VDC input, the family includes NSD05-48S3 at 3.96W, 3.3V, 1.2A; NSD05-48S5 at 5W, 5V, 1A; NSD05-48S12 at 5.04W, 12V, 0.42A; and NSD05-48S15 at 4.95W, 15V, 0.33A. For 9.2~36VDC input, the corresponding models are NSD05-12S3 at 3.96W, 3.3V, 1.2A; NSD05-12S5 at 5W, 5V, 1A; NSD05-12S12 at 5.04W, 12V, 0.42A; and NSD05-12S15 at 4.95W, 15V, 0.33A.
