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 SPUN02M-12 for 12V industrial control or instrumentation circuits?

Yes, it provides a fixed 12V output with a 2W power rating, which matches low-power control and instrumentation electronics. The input range is 10.8~13.2V, so it fits designs built around that source range.

Is the SPUN02M-12 appropriate for embedded systems that need an isolated-looking 12V rail in a compact space?

It is suited to compact embedded electronics because the package is 19.6 × 7.2 × 10.2 mm (L × W × H) and it provides a fixed 12V output with 3KVDC input-output isolation. It is an unregulated converter (10% load regulation), and the 2W rating keeps it in the low-power category for board-level use.

Can this converter power low-power 12V interfaces in automation equipment?

Yes, the 12V output and 2W power level align with low-power interfaces and auxiliary electronics in automation equipment. It is better matched to small control loads than to larger 12V devices.

Will the SPUN02M-12 handle wide temperature conditions in enclosed equipment?

The specified operating range is -40°C to +105°C, with load derating at high ambient per the derating curve, so it is designed for wide-temperature operation in protected equipment. Because no IP rating is listed, the specs do not indicate suitability for exposed outdoor placement.

How does the SPUN02M-12 compare with the 5V and 15V versions in the same series?

The SPUN02M family variants listed here are all 2W models, but they differ in output voltage and listed output current. SPUN02M-05 is 5V and 0~400mA, SPUN02M-12 is 12V and 0~167mA, and SPUN02M-15 is 15V and 0~134mA.
