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 SKMW20G-15 for a 15V industrial sensor or control circuit?

Yes, this unit delivers a constant 15V output and is rated for 20W with up to 1.33A output current. It is intended for applications that need a regulated 15V supply and fit within those electrical limits.

Is the SKMW20G-15 a good fit for compact embedded systems that require 15V power?

It is designed for compact installations with dimensions of 25.4 × 25.4 × 10.2 mm and a weight of 19g. The regulated 15V output can support embedded or control hardware that needs constant voltage within the 20W rating.

Can this model power low-current 15V automation devices from a broad input range?

Yes, the specified input range is 18-75VDC, and the output is 15V constant voltage at up to 1.33A. That makes it relevant for 15V automation devices that do not exceed 20W.

How does the SKMW20G-15 compare with other SKMW20G converters?

The SKMW20G-15 is a 20W converter with 15V output at 1.33A. Other listed SKMW20G models are the SKMW20G-03 at 3.3V and 4.5A, the SKMW20G-05 at 5V and 4A, and the SKMW20G-12 at 12V and 1.67A. All are in the same 20W series.

Can the SKMW20G-15 be used in hot, cold, or outdoor equipment enclosures?

The published operating temperature range is -40°C to +85°C, which supports use across a wide temperature span. No IP rating is provided, so resistance to dust or water exposure is not defined in the product specs.
