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

What is the Mean Well MDS02M-03N designed for?

The MDS02M-03N is a 2W SIP-package DC-DC converter intended for compact embedded power conversion in space-constrained equipment. This model provides a 3.3V output and is suited to B2B and industrial designs that need reinforced isolation and approved safety coverage.

What are the key electrical specifications of the MDS02M-03N?

This model is rated for 2W output power and provides a 3.3V output from a 12V nominal (10.8 to 13.2V) input. The output current range is 61 to 606mA, and the product is part of Mean Well's MDS02-N/MDD02-N SIP DC-DC converter family.

Is the MDS02M-03N suitable for medical or safety-sensitive equipment?

Yes. The series is medical safety approved to IEC60601-1 with 1xMOPP/2xMOOP coverage, and it is also approved to IEC62368-1/UL62368-1 and EAC TP TC 020/2011. It also specifies a patient leakage current of 2μA max and 6KVDC input-to-output isolation with reinforced insulation.

How does the MDS02M-03N handle harsh operating environments?

The MDS02M-03N is specified for an operating temperature range of -40°C to +95°C with load derating per the derating curve, making it appropriate for demanding industrial environments. Its compact SIP form factor also supports use in dense assemblies where board space is limited.

What protection features does the MDS02M-03N include?

This model includes continuous short-circuit protection with automatic recovery. Mean Well also recommends an external 500mA slow-blow fuse on the input.

How compact is the MDS02M-03N compared with other isolated DC-DC converter formats?

The MDS02M-03N uses a SIP package with dimensions of 19.7 x 7.1 x 11.5 mm and a weight of 2.8 g. Compared with larger board-mount converter formats, this makes it a compact option for applications where isolation and small size both matter.
