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 SFTN01N-15 in a 24V industrial control panel that needs a small 15V rail?

Yes, this converter is intended for applications with a 21.6~26.4VDC input and provides a fixed 15V output. Its 1W power rating and 67mA maximum output current make it better suited to low-power control, sensing, or interface circuits rather than larger loads.

Is this DC-DC converter suitable for embedded or automation modules that only need a very low 15V load?

It can fit low-power embedded or automation use cases where the required output is 15V and the load stays within 1W and 67mA. The output is unregulated (load regulation ±8%, line regulation 1.2% per 1% input change), so check that the downstream device tolerates this variation.

Can this model power a small isolated 15V section inside industrial electronics?

It is designed for small-power conversion with a 21.6~26.4VDC input and a fixed 15V output. With only 1W available, it is a fit for light-duty electronics sections and not for equipment that needs more than 67mA.

Is the SFTN01N-15 appropriate for indoor or outdoor equipment?

The listed specs include an operating temperature range of -40°C to +90°C, which supports use across a wide temperature span. However, no IP rating or enclosure protection level is provided here, so outdoor suitability is not specified by these specs alone.

How does the SFTN01N-15 compare with the other SFTN01N models?

Within the SFTN01N series, all listed models are 1W converters, but they differ in output. The SFTN01N-05 is 5V at 200mA, the SFTN01N-09 is 9V at 111mA, the SFTN01N-12 is 12V at 84mA, and this SFTN01N-15 is 15V at 67mA.
