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 SCWN06B-12 to power a 12V sensor or small industrial transmitter from a 18-36V bus?

Yes, this model is a constant-voltage DC-DC converter with 18-36V input and 12V output. Its 6W rating and 0.5A output current make it suitable for low-power 12V sensors, transmitters, or interface devices that stay within those limits.

Is the SCWN06B-12 suitable for embedded 12V control electronics in compact equipment?

It is a fit for embedded 12V electronics when the load needs regulated 12V and draws no more than 0.5A. The compact 31.8 × 20.3 × 10.2 mm size and 0.0125 kg weight also make it practical where board or enclosure space is limited.

Can this converter be used for a small 12V relay or actuator control circuit?

It can be used for a 12V control circuit if the total load stays within 6W and 0.5A output. This makes it better suited to light-duty control electronics than to higher-current 12V loads.

What is the difference between the SCWN06B-12 and the other SCWN06B models?

All SCWN06B models in this group are 6W converters with 18-36V input, but they differ in output. The SCWN06B-03 provides 3.3V at 1.2A, the SCWN06B-05 provides 5V at 1A, the SCWN06B-12 provides 12V at 0.5A, and the SCWN06B-15 provides 15V at 0.4A.

Is the SCWN06B-12 suitable for outdoor or high-temperature environments?

The operating temperature range is -40°C to +90°C, which supports use in demanding temperature conditions. No IP rating is listed in the provided specs, so the specs do not establish suitability for direct outdoor, wet, or dust-exposed use without added protection.
