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 DKMW30F-12 in a 12V vehicle or battery-based control system?

It is suited to systems with a 9-36V input range that need a ±12V constant-voltage output. That makes it relevant for 12V, 24V, or other DC platforms that fall inside that input window. The converter is rated for 30W with ±1.25A output current.

Is this model suitable for industrial electronics powered from a 24V DC bus?

Yes. A 24V source sits inside the 9-36V input range, and the converter provides a ±12V constant-voltage output. With a 30W rating in a 25.4 × 25.4 × 10.2 mm package, it fits lower-power industrial electronics that need voltage conversion on a compact footprint.

Can the DKMW30F-12 power embedded or automation modules that need regulated 12V?

Yes, if the modules require ±12V constant-voltage power and the load stays within 30W and ±1.25A. The 9-36V input range is useful in embedded and automation designs where the available DC supply can vary. Its small size also supports dense layouts.

Is the DKMW30F-12 appropriate for outdoor equipment cabinets?

The operating temperature range of -40°C to +85°C supports wide thermal conditions, but no IP rating is listed for this converter. That means it should not be treated as a weather-exposed or washdown product on its own. A protected enclosure is the better match when environmental sealing is required.

What is the difference between the DKMW30F-12 and DKMW30F-15?

Both are 30W converters with a 9-36V input range, 25.4 × 25.4 × 10.2 mm dimensions, 19.2g weight, -40°C to +85°C operating temperature, and a 3-year warranty. The DKMW30F-12 provides ±12V output at ±1.25A, while the DKMW30F-15 provides ±15V output at ±1A. The input range and package are the same, but the output voltage and current differ.
