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 MDD02M-05 in a 12V-class embedded system that needs ±5V rails?
Yes, this model is designed for a 10.8~13.2V input and provides an unregulated ±5V output. Its 2W rating makes it suitable for low-power embedded analog sections, interface boards, and isolated signal-conditioning circuits.
Is the MDD02M-05 suitable for industrial control electronics powered from a 12V nominal rail?
It is a match when the available source falls within 10.8~13.2V and the downstream circuit needs ±5V rails. The converter is rated at 2W and comes in a 19.5 × 9.8 × 12.5 mm package for compact PCB-level integration.
Can this converter be used on automation or instrumentation boards with tight space limits?
Yes, the 19.5 × 9.8 × 12.5 mm dimensions and 0.0042 kg weight make it practical for dense automation or instrumentation boards. It is intended for unregulated conversion from 10.8~13.2V input to ±5V output at 2W.
Is the MDD02M-05 intended for outdoor equipment or harsh environments?
The operating temperature range is -40°C to +85°C, so the thermal specification is broad. The provided specs do not list an IP rating, which means outdoor or exposed-environment suitability is not stated here.
How does the MDD02M-05 compare with other MDD02M series models?
The MDD02M-05 is the 2W ±5V model with ±20~200mA per output. The other MDD02M models share the 2W rating and 10.8~13.2V input: MDD02M-09 at ±9V, ±12~111mA; MDD02M-12 at ±12V, ±9~83mA; and MDD02M-15 at ±15V, ±7~67mA.
