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 NSD10-48D5 to power low-power industrial control electronics that need ±5V?
It can fit low-power industrial control circuits that need a constant-voltage ±5V output from a 22~72VDC input source. With a 10W rating and 1A per output, it is better aligned with compact control, interface, and signal-stage loads than higher-power electronics.
Is the NSD10-48D5 suitable for embedded analog or mixed-signal boards in automation equipment?
Yes, this model is positioned for compact embedded or analog support boards that need a ±5V output within a 10W power budget. Its 50.8 × 25.4 × 10.0 mm size also suits space-limited industrial or embedded assemblies.
Can this converter be used in legacy instrumentation that runs from a wide DC input range?
It is a reasonable fit when the equipment needs constant-voltage ±5V output and the available source falls within 22~72VDC. The 10W rating makes it more appropriate for lower-power instrumentation sections than for larger subsystems.
Is the NSD10-48D5 appropriate for outdoor or harsh-environment use?
No IP rating is listed in the provided specs, so exposed outdoor use or washdown use is not established from this data alone. The stated operating temperature range is -25°C to +70°C, which defines temperature capability but not water or dust protection.
How does the NSD10-48D5 compare with other NSD10 series models?
On the NSD10-D datasheet, the 9.8~36VDC input models are NSD10-12D5 (10W, ±5V, 1A per output), NSD10-12D12 (10.08W, ±12V, 0.42A) and NSD10-12D15 (9.9W, ±15V, 0.33A); the 22~72VDC input models are NSD10-48D5 (10W, ±5V, 1A), NSD10-48D12 (10.08W, ±12V, 0.42A) and NSD10-48D15 (9.9W, ±15V, 0.33A). All are dual-output units in the same 50.8 x 25.4 x 10 mm package with 1KVDC I/O isolation.
