  1. 1.All parameters are specified at normal input(L:5Vdc, M:12Vdc, N:24Vdc), rated load, 25℃ 70% RH ambient.
  2. 2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μf & 47μf capacitor.
  3. 3.Line regulation is measured from low line to high line at rated load.
  4. 4.Load regulation is measured from 10% to 100% rated load.
  5. 5.Patient leakage current(2μA max.) and reinforced isolation is based on a 250VAC, 50/60Hz system input voltage.
  6. 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 DC-DC converter for applications that need a regulated 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. The listed rated current is 40 mA, and the product belongs to Mean Well's MDS02L series in a SIP7 package.

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

Yes. The product description states it is medical safety approved to IEC60601-1 with 1xMOPP/2xMOOP and has low patient leakage current below 2 microamps. It also complies with IEC/UL62368-1 and carries CB, UL, EAC, CE, and UKCA safety certifications.

How much isolation does the MDS02L-03N provide?

The MDS02L-03N is specified with 6KVDC input-to-output isolation. The description identifies this as reinforced insulation, 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. 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 and overload protection that shuts down the output when rated power reaches 102% or more, then automatically recovers. These protections help support reliability in normal equipment operation.
