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 SFTN02M-15 for low-power 15V analog or signal-conditioning circuits?

Yes, it can suit low-power 15V analog or signal-conditioning circuits that need a constant-voltage output and remain within the 2W rating. This model converts a 10.8~13.2VDC input to 15V output for small electronics rather than larger loads.

Is the SFTN02M-15 a fit for embedded 15V support rails in industrial electronics?

It is suitable for embedded 15V support rails in compact industrial electronics where the load is light and regulated constant voltage is required. The 2W power level makes it more appropriate for control and interface functions than for power-hungry devices.

Can this converter be used in compact automation boards that require 15V output?

It can work in compact automation boards that need a 15V constant-voltage rail and operate from a 10.8~13.2VDC input. Its small 15.24 x 10.9 x 7.1 mm footprint is useful when available board area is limited.

What is the difference between the SFTN02M-15 and the other SFTN02M versions?

The main difference is the output rating. SFTN02M-05 is 5V at 400mA, SFTN02M-12 is 12V at 167mA, and SFTN02M-15 is 15V at 133mA. All models in this sibling group are rated for 2W.

Can the SFTN02M-15 be used outdoors or in wide-temperature environments?

Its specified operating range is -40°C to +100°C, so the temperature rating is broad for demanding environments. Still, there is no IP rating in the listed specs, so the product should not be treated as outdoor-rated or weather-protected without additional enclosure protection.
