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 DKMW20G-15 in a 24V or 48V automation system that needs 15V output?

Yes. The DKMW20G-15 accepts an 18-75V input range, so it can fit both 24V and 48V based DC systems. It delivers a 15V constant-voltage output with a 20W power rating.

Is this converter a good fit for embedded control boards that require 15V power?

It can be a practical fit where the source stays within 18-75V and the load needs a 15V constant-voltage rail. The compact 25.4 × 25.4 × 10.2 mm size and 19g weight help in space-constrained embedded designs. Its 20W rating also keeps it in the range of lower-power subsystems.

Can the DKMW20G-15 be used in industrial instrumentation that runs from a wide DC bus?

Yes, for instrumentation or control sections that need 15V constant-voltage power and stay within the 20W rating. The 18-75V input range supports use across a broad span of DC bus conditions. That makes it relevant in industrial equipment where the available supply is not fixed at one input level.

Can this model be used in cold or hot equipment enclosures?

The specified operating temperature range is -40°C to +85°C, so it is intended for demanding thermal conditions inside suitable equipment. No IP rating is listed, so that temperature range does not imply exposure to rain, dust, or washdown. It is better suited to protected enclosures than open outdoor mounting.

How does the DKMW20G-15 compare with the DKMW20G-12?

These two models share the same 20W rating, 18-75V input range, 25.4 × 25.4 × 10.2 mm dimensions, 19g weight, -40°C to +85°C operating temperature, and 3-year warranty. The DKMW20G-15 provides ±15V output with ±660mA listed output current, while the DKMW20G-12 provides ±12V output with ±830mA listed output current. The main distinction is the output voltage and listed output current.
