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-09 to power a 9V embedded subsystem from a 10.8~13.2V source?

Yes, this converter accepts 10.8~13.2VDC input and provides a fixed 9V output. With a 1W rating, it is aimed at low-power embedded, control, or monitoring circuits rather than higher-power 9V equipment.

Is the SFTN01M-09 suitable for a low-power automation or instrumentation board that needs 9V?

It can be suitable when the application needs a 9V rail and the available input is in the 10.8~13.2V range; note it is an unregulated converter (load regulation ±8%). The small 15.24 × 10.9 × 7.1 mm footprint also helps when board space is limited in instrumentation or automation hardware.

Would this model fit a compact test, measurement, or industrial interface device powered from a nominal 12V source?

It is designed for that type of low-power conversion because it turns 10.8~13.2V input into a fixed 9V output. The 1W rating and 0.0012 kg weight make it more appropriate for compact electronics than for larger power-demanding loads.

Can I use the SFTN01M-09 in outdoor equipment?

The operating temperature range is -40°C to +90°C, so the thermal specification is broad. However, the provided specs do not list an IP rating or enclosure protection level, so outdoor exposure suitability is not established here.

What is the practical difference between the SFTN01M-09 and the other SFTN01M outputs?

The difference is the output rating within the same 1W series. The SFTN01M-05 is 5V and 200mA, the SFTN01M-09 is 9V and 111mA, the SFTN01M-12 is 12V and 84mA, and the SFTN01M-15 is 15V and 67mA.
