Test conditions and notes5

1.All parameters are specified at normal input(E:5Vdc, 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 SCWN03, 25% to 100% rated load for DCWN03.
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 SCWN03E-05 for a 5V industrial control board?

Yes, this converter provides a constant 5V output with up to 0.6A available. That makes it appropriate for low-power 5V control electronics that fit within the 3W rating.

Is this model suitable for 5V embedded computing or interface modules?

It is intended for low-power 5V embedded and interface circuits that require constant-voltage output. The load needs to stay within 3W total and within the 0.6A output current rating.

Can the SCWN03E-05 power 5V automation logic in a small enclosure?

It can be used for compact 5V automation logic where space is limited, since the converter measures 31.8 × 20.3 × 10.2 mm. It is best matched to low-power electronics rather than higher-demand 5V equipment.

How does the SCWN03E-05 compare with the other SCWN03E output options?

Each SCWN03E unit in this series is rated at 3W and shares the same physical size of 31.8 × 20.3 × 10.2 mm. The SCWN03E-05 outputs 5V at 0.6A, while the sibling models are 3.3V at 0.6A, 12V at 0.25A, and 15V at 0.2A.

Can this 5V converter be used in outdoor applications?

The operating temperature range is -40°C to +90°C, so it supports wide-temperature environments. However, no IP rating is provided in the specs, so the product information does not indicate outdoor or water-exposed use.
