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 MDD01L-05 for a low-power 5V automation control board?

Yes, if the board needs a ±5V dual rail. The unit provides a fixed, unregulated ±5V output at 1W from a 4.5~5.5VDC input, which makes it a better fit for small electronics than for larger automation loads.

Is this converter appropriate for 5V industrial communication or monitoring circuits?

It can be used where a low-power ±5V supply is needed for monitoring, signaling, or communication subcircuits in industrial equipment. The key constraint is its 1W power rating (up to 100mA per output), so it should be reserved for compact electronic sections instead of full system loads.

Can the MDD01L-05 support 5V embedded peripherals in an OEM device?

It is a reasonable choice for low-power ±5V embedded peripherals, controller support circuits, or interface boards in OEM equipment. The converter provides a fixed ±5V output and operates across -40°C to +85°C (with load derating at higher temperatures, see the derating curve), which is useful for electronics deployed in varied operating environments.

Is the MDD01L-05 suitable for outdoor installations?

The operating temperature range is -40°C to +85°C (with load derating at higher temperatures, see the derating curve), so the temperature specification is broad. However, no IP rating is listed in the provided data, so these specs alone do not confirm outdoor exposure or weather-resistant use.

What are the main output choices in the MDD01L family compared with the MDD01L-05?

The 1W MDD01L siblings are MDD01L-09 at ±9V up to 56mA, MDD01L-12 at ±12V up to 42mA, and MDD01L-15 at ±15V up to 34mA. This model is the ±5V version rated at 1W, with up to 100mA per output.
