Test conditions and notes6
- 1.All parameters are specified at normal input(L:5Vdc, M:12Vdc, N:24Vdc), 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 10% to 100% rated load.
- 5.Patient leakage current(2μA max.) and reinforced isolation is based on a 250VAC, 50/60Hz system input voltage.
- 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 MDS02N-12 to generate 12V rail power inside a 24V industrial control panel?
Yes, this model is an unregulated DC-DC converter intended to provide 12V output from a 21.6~26.4Vdc input range. Its 2W power rating makes it better suited to low-power panel electronics than larger 12V loads.
Is the MDS02N-12 suitable for 12V embedded controller or sensor support circuits in automation equipment?
It can fit embedded or automation designs that need a 12V output and have a 21.6~26.4Vdc source available. With a 2W rating and a compact 19.5 x 9.8 x 12.5 mm package, it is aimed at space-constrained, low-power circuitry.
Can this converter be used in compact DIN-rail or machine-control electronics where board space is limited?
It is a strong fit where small size matters, because the body is only 19.5 x 9.8 x 12.5 mm and weighs 0.0042 kg. The electrical fit still depends on needing an unregulated 12V output within the 2W power limit.
Is the MDS02N-12 rated for outdoor or washdown environments?
The listed specs include an operating temperature range of -40C to +85C, but no IP rating is provided. That means temperature capability is broad, while outdoor or water-exposed suitability is not stated by the supplied specs.
How does the MDS02N-12 compare with the other MDS02N models?
All MDS02N models are 2W converters with 21.6~26.4V input. The other options are 5V at 40~400mA for MDS02N-05 and 15V at 13~133mA for MDS02N-15, while this model is the 12V version at 17~167mA.
