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-12 for low-power 12V electronics in embedded hardware?

This model is rated for a 4.5~5.5Vdc input and provides an unregulated 12V output at 2W. That makes it appropriate for low-power embedded hardware sections that require a 12V rail from that input range.

Is the MDS02L-12 suitable for 12V auxiliary circuits in industrial control equipment?

Yes, if the industrial control equipment has a 4.5~5.5Vdc source available and the auxiliary circuit fits within the 2W rating. It is intended for 12V support electronics rather than larger 12V power loads.

Can this converter be used for 12V automation or instrumentation modules?

It can be used where an automation or instrumentation module needs a 12V output from a 4.5~5.5Vdc input. Its compact size of 19.5 × 9.8 × 12.5 mm is useful where module space is tight.

Is the MDS02L-12 appropriate for harsh indoor environments?

The operating temperature is specified from -40°C to +85°C, which supports a wide range of indoor equipment conditions. Because no IP rating is listed, it is better suited to protected enclosures than exposed wet or outdoor environments.

What is the difference between the MDS02L-12 and the other MDS02L models?

The MDS02L family shown on the sheet is entirely 2W with 4.5~5.5V input. The other versions are MDS02L-05 at 5V and 40~400mA and MDS02L-15 at 15V and 13~133mA, while this model is 12V at 17~167mA.
