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 NSD10-48D15 for bipolar analog circuits or measurement electronics that need +/-15V?
Yes, it provides constant-voltage +/-15V output and is rated for 9.9W total power. It fits lower-power bipolar analog, measurement, and interface circuits that require +/-15V within that 9.9W rating.
Is the NSD10-48D15 suitable for industrial instrumentation or signal-conditioning boards?
It can be used where industrial instrumentation or signal-conditioning electronics need regulated +/-15V rails. The output is intended for compact loads, with a listed 9.9W power rating and 0.33A per output as provided in the product specs.
Can this model support +/-15V control electronics from a 22~72V input source?
Yes, the converter is specified for a 22~72V input range and constant-voltage +/-15V output. That makes it suitable for systems using a higher-voltage source while feeding lower-power +/-15V electronics.
Is the NSD10-48D15 practical for compact embedded or cabinet-mounted designs?
The unit measures 50.8 x 25.4 x 10.0 mm and weighs 0.02 kg, so it is well suited to compact layouts. It is a small-format option for designs that need a bipolar +/-15V converter with a 9.9W rating.
Can the NSD10-48D15 be used in outdoor equipment or only protected environments?
The listed operating temperature range is -25C to +70C, which supports demanding indoor industrial conditions. No IP rating is shown in the provided specs, so the product data does not present it as an outdoor-rated converter by itself.
What other NSD10 series models are available alongside the NSD10-48D15?
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.
