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 SCWN03B-15 to power a 15V industrial signal-conditioning or analog interface board?

Yes, this model provides a constant 15V output at up to 0.2A with 3W total power. That fits low-power 15V control, analog, or interface circuits as long as the load stays within 0.2A and the source is within the listed 18-36V input range.

Is the SCWN03B-15 suitable for a small embedded controller that needs 15V from an 18-36V supply rail?

It can be suitable for low-power embedded electronics that specifically require a regulated 15V rail. The key limits are its 3W rating, 0.2A maximum output current, and 18-36V input range.

Can this 15V converter be used in compact automation equipment with limited space?

Yes, the package is compact at 31.8 × 20.3 × 10.2 mm and weighs 12.3 g, so it fits space-constrained control assemblies more easily than larger power modules. It is still a 3W converter, so it is intended for low-power 15V sections rather than higher-current automation loads.

Is the SCWN03B-15 a good fit for low-current 15V instrumentation inside a machine or control cabinet?

For low-current 15V instrumentation, it is aligned with that type of use because it delivers 15V constant voltage at up to 0.2A. Buyers should size the load against the full 3W limit rather than treating it like a general-purpose higher-power supply.

Can the SCWN03B-15 be used outdoors or in hot and cold industrial environments?

The operating temperature range is wide at -40°C to +90°C, which supports demanding temperature conditions. However, no IP rating is listed in the provided specs, so outdoor exposure or moisture protection is not established by this product data.

How does the SCWN03B-15 compare with the other SCWN03B models?

All SCWN03B versions in this group are rated at 3W. The SCWN03B-03 outputs 3.3V at 0.6A, the SCWN03B-05 outputs 5V at 0.6A, the SCWN03B-12 outputs 12V at 0.25A, and the SCWN03B-15 outputs 15V at 0.2A.
