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 MDD02L-09 for a 5V-powered analog interface that needs ±9V rails?
Yes, this converter is designed for a 4.5~5.5V input and provides an unregulated ±9V output. With a 2W rating, it is better suited to low-power analog interface, embedded signal-conditioning, or isolated measurement sections.
Is the MDD02L-09 a fit for industrial control cards with ±9V analog stages?
It can be used where the card already has a 4.5~5.5V source and the analog stage requires ±9V rails. The 2W power rating and 19.5 × 9.8 × 12.5 mm size make it more appropriate for compact control electronics than larger power sections.
Would the MDD02L-09 work in embedded test and measurement equipment?
Yes, embedded test and measurement boards that run from 4.5~5.5V and need ±9V rails are the kind of low-power application this part fits. The unregulated ±9V output, 2W rating, and 0.0042 kg weight align with compact PCB-level use.
Can this converter be used in cold or hot industrial enclosures?
The specified operating range is -40°C to +85°C, which supports use across a wide temperature window. No IP rating is provided in the supplied specs, so suitability for outdoor exposure or washdown environments is not stated here.
What are the differences between the MDD02L-09 and the other MDD02L versions?
The MDD02L-09 is the 2W ±9V model with ±12~111mA per output. The other MDD02L models share the 2W rating and 4.5~5.5V input: MDD02L-05 at ±5V, ±20~200mA; MDD02L-12 at ±12V, ±9~83mA; and MDD02L-15 at ±15V, ±7~67mA.
