Test conditions and notes6
  1. 1.All parameters are specified at normal input(L:5Vdc, M:12Vdc, N:24Vdc), rated load, 25℃ 70% RH ambient.
  2. 2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μf & 47μf capacitor.
  3. 3.Line regulation is measured from low line to high line at rated load.
  4. 4.Load regulation is measured from 10% to 100% rated load.
  5. 5.Patient leakage current(2μA max.) and reinforced isolation is based on a 250VAC, 50/60Hz system input voltage.
  6. 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-12 for industrial instrumentation that needs ±12V rails from a 5V source?

Yes, this model is built for 4.5~5.5V input and provides an unregulated ±12V output. Its 2W rating suits low-power instrumentation, isolated signal-conditioning, and embedded analog sections rather than heavier power loads.

Is the MDD02L-12 suitable for embedded data acquisition or measurement boards?

It is a practical fit for embedded measurement boards that have a 4.5~5.5V input rail and need ±12V rails locally. The converter is compact at 19.5 × 9.8 × 12.5 mm and weighs 0.0042 kg, which helps in dense board layouts.

Can this converter be used for analog I/O sections in automation equipment?

Yes, analog I/O sections that require ±12V rails and operate from a 4.5~5.5V source are aligned with this part's specs. The output is unregulated, and the unit is rated at 2W with up to ±83mA per output.

Is the MDD02L-12 rated for outdoor control boxes or exposed environments?

The temperature specification is -40°C to +85°C, so the thermal range is broad. The provided data does not include an IP rating, so outdoor or exposed-environment suitability is not specified by these specs.

How does the MDD02L-12 compare with the rest of the MDD02L family?

The MDD02L-12 is the 2W ±12V model with ±9~83mA per output. The other MDD02L models share the 2W rating and 4.5~5.5V input: MDD02L-05 at ±5V, ±20~200mA; MDD02L-09 at ±9V, ±12~111mA; and MDD02L-15 at ±15V, ±7~67mA.
