Test conditions and notes6

1.All parameters are specified at normal input(K:3.3Vdc, 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: 220uF/100V.

FAQ

Can I use the SBTN01M-09 for a low-power 9V industrial sensor interface or signal module?

Yes, this converter provides a fixed 9V output rated for 111mA and 1W. It is suited to low-power sensor interface, monitoring, or signal-stage circuits that specifically need 9V and remain within that output rating.

Is the SBTN01M-09 a fit for embedded electronics that need a small 9V rail from a 12V DC source?

It is intended for a 10.8-13.2VDC input and produces an isolated, unregulated 9V output (load regulation ±8%). With a 111mA output limit and 1W power rating, it fits light embedded loads rather than larger 9V subsystems.

Can this model be used in compact automation assemblies where size matters?

Yes, the converter measures 12.9 x 10.9 x 7.1 mm and weighs 0.0011 kg, so it works well where board space is limited. It is most appropriate when the application only needs a low-power 9V output up to 111mA.

Will this converter handle broad temperature conditions in control equipment?

The specified operating temperature range is -40°C to +90°C, with load derating at high ambient temperature per the derating curve, which supports use across a wide temperature span. No IP rating is provided, so temperature capability does not by itself indicate suitability for exposed outdoor placement.

What are the key differences between the SBTN01M-09 and the rest of the SBTN01M family?

The SBTN01M family keeps the same 1W rating while changing output voltage and current. The sibling options are 3.3V at 300mA for the SBTN01M-03, 5V at 200mA for the SBTN01M-05, 12V at 84mA for the SBTN01M-12, and 15V at 67mA for the SBTN01M-15, while this version is 9V at 111mA. Note that the 9V models are not covered by the UL62368-1 approval.
