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 MDS02L-05 to provide 5V power for embedded electronics from a 5V-class source?

This converter is specified for a 4.5~5.5Vdc input and provides an unregulated 5V output at 2W. That makes it suitable for low-power embedded 5V electronics when the available source falls within that input range.

Is the MDS02L-05 suitable for 5V industrial interface circuits in compact equipment?

It can be used for 5V interface circuitry in compact equipment where the source is 4.5~5.5Vdc and the load fits within the 2W rating. The 19.5 × 9.8 × 12.5 mm dimensions support use in dense industrial or embedded layouts.

Can this model support low-power 5V automation control electronics?

Yes, it is intended for an unregulated 5V output and a 2W power level from a 4.5~5.5Vdc input. That profile fits low-power automation control electronics rather than higher-power 5V subsystems.

Is the MDS02L-05 meant for outdoor installations?

The published operating temperature range is -40°C to +85°C, so the temperature specification is broad. No IP rating is provided in the specs, so it should be considered for protected indoor or enclosed equipment use rather than direct outdoor exposure.

How does the MDS02L-05 compare with other MDS02L versions?

All MDS02L models are 2W with 4.5~5.5V input. The series includes MDS02L-12 at 12V and 17~167mA and MDS02L-15 at 15V and 13~133mA, while this MDS02L-05 version is 5V and 40~400mA.
