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 MDS02L-03N designed for?

The Mean Well MDS02L-03N is a 2W SIP package, medical grade unregulated DC-DC converter for applications that need a 3.3V DC output in a compact module format. It is suited to space-constrained electronic equipment where reinforced isolation and certified safety performance are important.

What are the key electrical specifications of the MDS02L-03N?

This model is rated for 2W output power and provides a 3.3V DC output from a 5V nominal (4.5 to 5.5V) input. The output current range is 61 to 606mA, and the product belongs to Mean Well's MDS02-N series in a SIP package.

Is the MDS02L-03N suitable for medical or safety-sensitive equipment?

Yes. The sheet states medical safety approval to IEC60601-1 with 1xMOPP/2xMOOP and a patient leakage current of 2μA max. It is also approved to IEC62368-1/UL62368-1 and EAC TP TC 020/2011.

How much isolation does the MDS02L-03N provide?

The MDS02L-03N is specified with 6KVDC input-to-output withstand voltage. The sheet identifies its isolation as reinforced (based on a 250VAC system input voltage), which helps differentiate it from lower-isolation DC-DC converter modules.

What operating environment can the MDS02L-03N handle?

This converter is rated for an operating temperature range of -40°C to +95°C with free-air convection cooling and load derating at higher temperatures per the derating curve. That makes it suitable for demanding industrial and embedded environments where wide temperature tolerance is required.

Does the MDS02L-03N include built-in protection features?

Yes. It includes continuous short-circuit protection with automatic recovery, and Mean Well recommends an external 500mA slow-blow input fuse. These measures help support reliability in normal equipment operation.
