Test conditions and notes5

1.All parameters are specified at normal input(A:12Vdc, B:24Vdc, C:48Vdc), 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 for SCWN06, 25% to 100% rated load for DCWN06.
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)

FAQ

Can I use the SCWN06C-03 to derive 3.3V logic power from a 48V or 60V DC system?

Yes, this model is built for 36-72V input and provides a constant 3.3V output. With 6W power and up to 1.2A output current, it suits low-power logic, MCU, and digital interface circuits on higher-voltage DC systems.

Is the SCWN06C-03 suitable for embedded controllers or communication boards that need 3.3V?

It is appropriate for embedded 3.3V electronics when the load stays within 1.2A and the total output stays within 6W. That makes it a practical fit for compact controller boards, communication modules, and digital control sections.

Can this converter power a 3.3V sensor cluster in industrial or automation equipment?

It can support a 3.3V sensor or control cluster if the combined demand remains within 6W and 1.2A. The 36-72V input range also makes it suitable where the upstream DC bus is higher than standard low-voltage control rails.

What are the main differences between the SCWN06C-03 and the other SCWN06C versions?

All SCWN06C variants are 6W converters with 36-72V input, but the outputs differ. The SCWN06C-03 is 3.3V at 1.2A, the SCWN06C-05 is 5V at 1A, the SCWN06C-12 is 12V at 0.5A, and the SCWN06C-15 is 15V at 0.4A.

Is the SCWN06C-03 meant for outdoor use or wide-temperature industrial enclosures?

The specified operating range is -40°C to +90°C, which supports wide-temperature operation. No IP rating is listed, so the provided specs do not confirm direct outdoor exposure or protection against water and dust.
