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 SCWN03C-15 for a 15V analog or instrumentation circuit on a 36-72V system?

Yes, this model outputs a constant 15V and supports up to 0.2A, which fits low-power analog or instrumentation sections. The application also needs to stay within the 3W rating and use a source inside the listed 36-72V input range.

Is the SCWN03C-15 suitable for a small 15V control rail in industrial electronics?

It is intended for low-power 15V electronics rather than larger control loads, because the maximum output current is 0.2A. For compact 15V rail needs within 3W, it is aligned with that requirement.

Can this converter power a 15V interface board inside a compact embedded or automation product?

Yes, the compact 31.8 × 20.3 × 10.2 mm package helps in space-limited designs, and the converter provides regulated 15V output. The load must remain within 0.2A and 3W for the part to be properly sized.

Would the SCWN03C-15 be a match for low-current 15V electronics on a 48V-class bus?

It can be, because the specified input range is 36-72V and the output is 15V constant voltage. It is best suited to low-current electronics that do not exceed the stated 0.2A output limit.

Can the SCWN03C-15 be used in outdoor equipment or wide-temperature enclosures?

The unit is rated for operation from -40°C to +90°C, so the temperature specification supports demanding thermal environments. The product data does not list an IP rating, so outdoor sealing or water ingress protection is not confirmed.

How does the SCWN03C-15 differ from the other SCWN03C versions?

The family shares the same 3W power class and 36-72V input range, but each model has a different output. SCWN03C-03 is 3.3V at 0.6A, SCWN03C-05 is 5V at 0.6A, SCWN03C-12 is 12V at 0.25A, and SCWN03C-15 is 15V at 0.2A.
