Test conditions and notes5

1.All parameters are specified at normal input(F:24Vdc, G: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 0% to 100% rated load.
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 SKMW30G-05 for 5V industrial controllers or interface electronics?

Yes, it provides a constant 5V output with up to 6A and a total power rating of 30W. That makes it suitable for 5V industrial controllers, interface electronics, and embedded boards that stay within those output limits.

Is the SKMW30G-05 a fit for USB-adjacent or logic-level equipment inside industrial systems?

For equipment that requires a regulated 5V rail, this model offers 5V constant voltage and up to 6A. Its 18-75V input range also makes it useful where the source bus is higher than the final logic or control voltage.

Can this converter power compact automation modules with moderate 5V current demand?

It can support compact automation modules that need 5V power, as long as the load does not exceed 6A or 30W. The small 25.4 x 25.4 x 10.2 mm package also helps in dense control assemblies.

Is the SKMW30G-05 suitable for outdoor enclosures?

The operating temperature range is -40C to +85C, which covers a broad thermal envelope. However, no IP rating is listed in the provided specs, so outdoor exposure protection is not defined by the product data shown here.

How does the SKMW30G-05 compare with the other SKMW30G models?

The series keeps the same 30W class and 18-75V input range across all four G-type versions. The available outputs are 3.3V at 7.5A, 5V at 6A, 12V at 2.5A, and 15V at 2A.
