Test conditions and notes6

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 10% 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)
6.An external input filter capacitor is required if the module has to meet BS EN/EN61000-4-4, BS EN/EN61000-4-5. The filter capacitor Power Mate suggest: 470μF/100V.

FAQ

Can I use the SFTN01M-12 in a compact 12V industrial control or monitoring circuit?

It can fit low-power 12V control or monitoring sections that need a fixed 12V output. This model is rated for 1W with a 12V output and 84mA maximum output current, so it is best suited to very small auxiliary loads rather than larger control hardware.

Is the SFTN01M-12 suitable for embedded 12V electronics inside space-limited equipment?

Yes, its 15.24 x 10.9 x 7.1 mm size and 0.0012 kg weight make it appropriate where board or enclosure space is tight. The fixed 12V output and 1W power rating mean it is intended for small embedded 12V sections, not higher-power subsystems.

Can this converter be used for a small 12V automation signal interface?

It may be appropriate for a small automation interface that needs a 12V output and draws no more than 84mA; note the output is unregulated (load regulation ±8%). Because the unit is only 1W, it is better matched to light-duty signal or interface tasks than to larger automation loads.

Is the SFTN01M-12 intended for outdoor or harsh-environment use?

The operating temperature range is -40°C to +90°C, so the temperature specification is broad. However, no IP rating is listed in the provided specs, so indoor or outdoor enclosure protection is not specified by this data.

How does the SFTN01M-12 compare with other SFTN01M models?

Within the SFTN01M series, the listed siblings are SFTN01M-05 at 1W, 5V, 200mA; SFTN01M-09 at 1W, 9V, 111mA; and SFTN01M-15 at 1W, 15V, 67mA. The SFTN01M-12 version is the 1W, 12V model with 84mA output current.
