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 no 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. Derating to 80% load is needed for NSD15-48D series at 18Vdc input voltage. Full output wattage can be acquired when the input voltage is higher than 20Vdc.
- 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 NSD15-48D15 for equipment that requires a ±15V output from a high-input-voltage source?
Yes, if the equipment requires constant-voltage ±15V output and the load stays within 15W. This converter is specified for 18~72V input, so it is suited to systems already operating in that higher input range.
Is this converter suitable for industrial analog electronics that need ±15V power?
It can fit industrial analog electronics that are designed for constant ±15V supply and remain within the 15W power rating. The 18~72V input range also distinguishes it from lower-input models in the same series.
Can the NSD15-48D15 be used in automation or embedded systems with an 18~72V source?
Yes, when the downstream electronics require a constant ±15V output and do not exceed the 15W limit. Full output is available above 20V input; at 18V input the load must be derated to 80%.
Will the NSD15-48D15 handle harsh temperature conditions or outdoor placement?
Its operating temperature range is -25°C to +70°C, with storage rated at -40°C to +85°C. No IP rating is published, so the specifications do not verify outdoor-exposed use.
What are the sibling options in the NSD15 series compared with the NSD15-48D15?
The NSD15-D sheet offers ±5V at 1.5A and 15W, ±12V at 0.62A and 14.88W, and ±15V at 0.5A and 15W, each in a 9.4~36V input and an 18~72V input version. The NSD15-48D15 is the 18~72V input, ±15V, 15W model. That makes it the higher-input counterpart to the 9.4~36V NSD15-12D15 (±15V, 0.5A).
