Test conditions and notes5

1.All parameters are specified at normal input(L:5Vdc, M:12Vdc, N:24Vdc), rated load, 25℃ 70% RH ambient.
2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μf & 47μf capacitor.
3.Line regulation is measured from low line to high line at rated load.
4.Load regulation is measured from 20% to 100% rated load.
5.The final equipment must be re-confirm that it still meet EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”(as available on http://www.meanwell.com)

FAQ

Can I use the SPUN02N-15 for a 15V analog or measurement circuit inside industrial equipment?

Yes, it fits low-power 15V analog, measurement, and signal-conditioning circuits that need a fixed 15V output, keeping in mind it is unregulated (10% load regulation). The converter is rated for 2W and accepts a 21.6~26.4VDC input range.

Is this 15V converter a good choice for embedded controller daughterboards or compact automation modules?

It is well suited to compact electronics because the body is only 19.6 × 7.2 × 10.2 mm (L × W × H) and the weight is 2.7g. That makes it practical for small embedded boards and tightly packed automation modules that need 15V output.

Can the SPUN02N-15 be used as an auxiliary 15V rail for low-power industrial controls?

Yes, it can serve as a small auxiliary supply where the source is within the 21.6~26.4VDC input range and the load needs a fixed 15V output. Its 2W rating keeps it in the low-power category for controls, instrumentation, and embedded support circuits.

Would this model work for isolated low-power electronics in automation or telecom assemblies that require 15V?

It is appropriate for low-power electronics that specifically require 15V output and do not exceed the converter's 2W rating, and it provides 3KVDC input-output isolation. The input range is 21.6~26.4VDC, so it is intended for systems built around a 24V DC source.

Can the SPUN02N-15 be used in outdoor equipment cabinets or wide-temperature installations?

The specified operating range is -40°C to +105°C, with load derating at high ambient per the derating curve, which supports wide-temperature applications. No IP rating is provided in the specs, so the product data does not indicate direct exposure suitability for rain, washdown, or open outdoor mounting.

What is the difference between the SPUN02N-15 and the other SPUN02N versions?

All listed siblings are 2W models, but they differ in output voltage and current. The SPUN02N-05 is 5V and 0~400mA, the SPUN02N-12 is 12V and 0~167mA, and the SPUN02N-15 is 15V and 0~134mA.
