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 type of product is the Mean Well MDS02L-05N?

The Mean Well MDS02L-05N is a 2W SIP-package DC-DC converter module with a regulated 5V output. It is part of Mean Well's MDS02L series and is designed for compact embedded power applications that need isolated DC conversion.

What are the key output and power specifications of the MDS02L-05N?

This model provides a 5V DC output and is rated for 2W of output power. The listed rated current is 40 mA, and the product is intended for low-power DC-DC conversion in compact electronic designs.

Is the MDS02L-05N suitable for medical or safety-sensitive equipment?

Yes, this model is described as medically safety approved to IEC60601-1 with 1xMOPP/2xMOOP support. It also features reinforced insulation with 6KVDC input-to-output isolation and low patient leakage current below 2 microamps, which makes it relevant for medical-related applications where those approvals matter.

How does the MDS02L-05N perform in harsh temperature environments?

The MDS02L-05N has an operating temperature range of -40°C to +95°C. That wide range makes it suitable for equipment that may face cold starts, enclosed electronics, or demanding industrial operating conditions.

What protection features does the MDS02L-05N include?

This converter includes continuous short-circuit protection for long-duration fault conditions. It also has overload protection that shuts down the output when rated power reaches 102% or higher, then recovers automatically.

What certifications and compliance marks are listed for the MDS02L-05N?

The product lists CB, UL, EAC, CE, and UKCA safety certifications. It is also stated to comply with IEC/UL62368-1 and IEC60601-1, except where noted in the source description for certain output variants.
