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 DKMW30G-15 in a 24V or 48V industrial control system that needs 15V rails?

This model is designed for applications with an 18-75VDC input range and a dual ±15V output. With 30W power and ±1A output current, it fits control, automation, and embedded systems that specifically require ±15V constant-voltage rails within that input window.

Is the DKMW30G-15 suitable for embedded boards or instrumentation that need isolated 15V power in a compact space?

It is a compact 30W DC-DC converter with 25.4 × 25.4 × 10.2 mm dimensions and a 19.2g weight. That size and dual ±15V, ±1A output make it relevant for dense embedded or instrumentation designs where ±15V rails are required.

Can this converter be used for industrial analog or automation hardware that runs on 15V?

It can fit automation or industrial electronics that need a dual ±15V output at up to ±1A. The 30W rating and 18-75VDC input range make it more appropriate for control hardware than for higher-power 15V loads.

Is the DKMW30G-15 suitable for outdoor or harsh-temperature installations?

The specified operating temperature is -40°C to +85°C, which supports use across a wide temperature range. No IP rating is listed, so outdoor or washdown suitability is not established from the provided specs and protected enclosure use should be evaluated separately.

How does the DKMW30G-15 compare with the DKMW30G-12?

Both models are 30W converters in the same series. The DKMW30G-15 provides ±15V output at ±1A, while the DKMW30G-12 provides ±12V output at ±1.25A.
