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 SFTN02L-15 to create a 15V rail from a 4.5-5.5VDC source?

Yes, this converter is designed for a 4.5-5.5VDC input and gives a constant 15V output. With a 2W power rating and a listed 133mA output current, it is intended for small 15V loads rather than higher-power devices.

Is this converter appropriate for low-power 15V sections in industrial or automation electronics?

It fits low-power applications that need a regulated 15V output from a 4.5-5.5VDC source. The 2W rating makes it suitable for compact control, signal, or interface electronics that stay within the converter's output limits.

Can the SFTN02L-15 be used in embedded systems that need a small constant-voltage 15V supply?

Yes, if the embedded design needs a constant 15V output and the available input falls within 4.5-5.5VDC. This model is better suited to light electronic loads because its total output power is 2W.

What kind of space claim does this model have in compact equipment?

The body size is 15.24 × 10.9 × 7.1 mm and the weight is 0.0012 kg. Those dimensions support use in dense assemblies where a small isolated power component is needed.

Is the SFTN02L-15 rated for indoor only or for outdoor use too?

The specifications show an operating temperature range of -40°C to +100°C. However, there is no IP rating listed, so the provided data does not establish outdoor exposure or water and dust protection.
