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 MDD01M-12 in a 12V nominal industrial controller that needs ±12V output rails?

Yes, this converter is designed for a 10.8~13.2VDC input and provides a fixed ±12V output. Its 1W power rating and up to 42mA per output make it suitable for low-power controller, interface, or conditioning sections that need ±12V.

Is the MDD01M-12 a good fit for embedded analog circuitry powered from a 12V DC source?

It is appropriate for embedded analog circuits that need a ±12V rail and stay within the 1W and 42mA-per-output limits. The compact 19.5 × 9.8 × 12.5 mm package supports use on small embedded boards.

Can this model be used in compact automation monitoring hardware where space and weight matter?

The converter measures 19.5 × 9.8 × 12.5 mm and weighs 0.0042 kg, so it suits dense monitoring and automation assemblies. Its fixed ±12V output from a 10.8~13.2VDC input is aimed at low-power electronics rather than larger loads.

Is the MDD01M-12 suitable for indoor enclosures exposed to low and high temperatures?

The specified operating temperature range is -40°C to +85°C (with load derating at higher temperatures, see the derating curve), which covers demanding indoor equipment conditions. No IP rating appears in the provided specs, so it should be used in protected enclosures instead of exposed outdoor locations.

How does the MDD01M-12 compare with other models in the same series?

The 1W MDD01M family also includes ±5V at up to 100mA for MDD01M-05, ±9V at up to 56mA for MDD01M-09, and ±15V at up to 34mA for MDD01M-15. The MDD01M-12 is the ±12V version rated at up to 42mA per output.
