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 MDD02N-05 in a 24V control cabinet to supply low-power 5V electronics?
Yes, this model is designed around a 21.6~26.4V input range and an unregulated ±5V output, which aligns with 24V-class control systems that need low-power ±5V rails. Its 2W rating makes it appropriate for small embedded electronics rather than larger loads.
Is the MDD02N-05 a fit for microcontroller or logic sections in industrial automation equipment?
It can be a good fit for board-level microcontroller or logic sections when the available source is within 21.6~26.4V and the circuit only needs a 2W ±5V supply. The small 19.5 x 9.8 x 12.5 mm dimensions help in dense automation assemblies.
Can this converter be used for low-power digital sensor interfaces on a 24V machine?
Yes, it is suitable for low-power digital sensor interface electronics that need ±5V rails from a 24V-class source. The 21.6~26.4V input window and unregulated ±5V output match that kind of embedded control application well.
Is the MDD02N-05 suitable for outdoor equipment or only protected enclosures?
The temperature rating of -40°C to +85°C supports operation across a wide industrial temperature range. No IP rating is listed, so the published specs do not confirm suitability for direct outdoor exposure or wet and dusty locations without enclosure protection.
