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 DKMW20F-15 for a 15V industrial or embedded control circuit?

It is intended for constant ±15V output applications with a 9-36VDC input range. That makes it a fit for low-power industrial, embedded, or automation electronics that stay within 20W and the listed ±660mA output current.

Is the DKMW20F-15 suitable for 15V automation electronics where input voltage may vary?

This model accepts 9-36VDC input, so it suits applications that need a wider allowable input range than a narrow low-voltage design. On the output side, it provides constant ±15V up to its 20W rating.

Would the DKMW20F-15 fit in space-limited embedded hardware?

Its dimensions are 25.4 × 25.4 × 10.2 mm, so it can fit compact boards and dense electronic assemblies. It is designed for constant-voltage ±15V use cases within 20W.

Can the DKMW20F-15 be used in outdoor equipment cabinets?

The operating temperature range is -40°C to +85°C, which supports use across a broad temperature span. However, no IP rating is given, so the product data does not confirm suitability for exposed outdoor or washdown environments.

How does the DKMW20F-15 compare with the DKMW20F-12?

The two listed DKMW20F models share the same 20W power rating, 9-36VDC input range, 25.4 × 25.4 × 10.2 mm size, 19g weight, and -40°C to +85°C operating range. The difference in the listed specs is output: the DKMW20F-15 is ±15V at ±660mA, while the DKMW20F-12 is ±12V at ±830mA.
