Test conditions and notes6

1.All parameters are specified at normal input(A:12Vdc, B:24Vdc, C: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.
5.2xMOPP base on a working voltage of 250Vac between Primary to Secondary.
6.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 MDS15A-24 for 24V industrial control electronics that need constant voltage?

Yes, this model provides a constant-voltage 24V output and is rated for 15W. It is intended for lower-power 24V electronics when the available source falls within the stated 9-18Vdc input range.

Is the MDS15A-24 suitable for compact 24V automation interfaces or signaling devices?

It can be a fit for small 24V automation loads where constant voltage is required and the total demand stays within 15W. The published input range is 9-18Vdc, so source compatibility needs to match that range.

Can this converter be used for embedded or industrial systems standardized on 24V rails?

It is aimed at applications that need regulated 24V output in a compact format rather than higher-power 24V distribution. The deciding specs are 24V output, 15W power, and 9-18Vdc input.

Is the MDS15A-24 appropriate for outdoor equipment or exposed plant environments?

The operating temperature range is listed as -40C to +90C (load derating applies at higher ambient temperatures per the derating curve), which supports wide-temperature use. No IP rating is provided in the specs, so the data does not confirm direct outdoor exposure or water-resistant use.

How is the MDS15A-24 positioned within the MDS15A series?

Every MDS15A version is rated at 15W with 9-18Vdc input. The series includes MDS15A-05 at 5V and 3A, MDS15A-12 at 12V and 1.25A, MDS15A-15 at 15V and 1A, and MDS15A-24 at 24V and 625mA.
