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 NSD10-48D12 for bipolar analog or signal-conditioning circuits in industrial equipment?
Yes, this model provides constant-voltage +/-12V output with a 10.08W rating. It is suited to lower-power bipolar analog, signal-conditioning, and interface circuits that need +/-12V and stay within the listed 10.08W output rating.
Is the NSD10-48D12 suitable for control and monitoring boards that need +/-12V rails?
It can be used for control, monitoring, and instrumentation boards that require +/-12V output. The converter is intended for compact loads within its 10.08W capacity rather than higher-power +/-12V subsystems.
Can this converter be used in equipment with a 22~72V input bus and +/-12V electronics?
Yes, the specified input range is 22~72V and the output is constant-voltage +/-12V. That makes it relevant for systems built around a higher-voltage input bus feeding lower-power bipolar electronics.
Does the NSD10-48D12 work well in compact industrial assemblies?
Its dimensions are 50.8 x 25.4 x 10.0 mm and its weight is 0.02 kg, so it is small enough for dense layouts. That is useful when a compact +/-12V converter is needed inside a control enclosure or embedded assembly.
Is the NSD10-48D12 meant for outdoor use or temperature-demanding indoor equipment?
The operating temperature range is -25C to +70C, so it is specified for a broad industrial indoor temperature range. No IP rating is listed, so the provided specs do not define it as outdoor rated or weather-sealed.
How does the NSD10-48D12 compare with other NSD10 converter options?
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.
