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 SFTN01L-15 for a low-power 15V analog or industrial control circuit from a 4.5~5.5V source?

Yes, this model provides a fixed 15V output from a 4.5~5.5V input source. With a 1W rating, it is intended for low-power analog, control, or interface circuitry rather than higher-power 15V equipment.

Is the SFTN01L-15 suitable for embedded measurement electronics that need a 15V rail?

It can be used where the electronics require a 15V output and the available input is within 4.5~5.5V; as an unregulated converter its load regulation is ±8%. The output current is listed as 67mA max., so it is positioned for lower-power measurement or signal-chain use.

Would this converter make sense in a compact automation module with limited board space?

The 15.24 × 10.9 × 7.1 mm package is compact, which helps in small automation and embedded assemblies. Its 1W fixed-output design is better aligned with dedicated low-power 15V rails than with broad system-level power conversion.

Is the SFTN01L-15 intended for outdoor installations or washdown areas?

The operating temperature range is -40°C to +90°C, so the temperature specification is broad. However, no IP rating or enclosure class is listed in the provided specs, so the product data does not establish suitability for exposed outdoor or washdown environments.

What changes across the SFTN01L family besides the part number?

The family keeps the 1W platform and changes the output rating by model. The SFTN01L-05 is 5V and 200mA, the SFTN01L-09 is 9V and 111mA, the SFTN01L-12 is 12V and 84mA, and the SFTN01L-15 is 15V and 67mA.
