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 MDS01L-03N designed for?

The Mean Well MDS01L-03N is a 1W SIP-package DC-DC converter module intended for regulated low-power DC conversion in compact equipment. This specific model provides a 3.3V DC output and is suited to space-constrained B2B and embedded applications where reinforced isolation and medical-related safety approvals matter.

What are the key electrical specifications of the MDS01L-03N?

This model is rated for 1W output power and provides a 3.3V DC output. The listed rated current is 30 mA, and the series supports short circuit protection and overload shutdown with automatic recovery when rated power reaches 102% or more.

Is the MDS01L-03N suitable for medical or safety-sensitive equipment?

Yes, the product description states that the MDS series is medical safety approved to IEC60601-1 with 1xMOPP/2xMOOP and low patient leakage current below 2 microamps. It also carries CB, UL, EAC, CE, and UKCA safety certifications covering 62368-1 and 60601-1.

How does the MDS01L-03N handle harsh temperature conditions?

The MDS01L-03N has an operating temperature range of -40°C to +95°C. That wide range makes it appropriate for industrial and commercial equipment exposed to demanding thermal environments, provided the overall system is designed within the product's rated limits.

What makes the MDS01L-03N different from a general-purpose non-isolated converter?

A key differentiator is its 6KVDC input-to-output isolation with reinforced insulation, which is a stronger safety feature than many basic low-power converter options. It also combines that isolation with a compact SIP7 package, medical-related approvals, and low leakage current, making it a stronger fit for sensitive electronic systems.

What size is the Mean Well MDS01L-03N?

The listed dimensions are 19.7 x 7.1 x 11.5 mm. Its compact SIP7 form factor helps it fit into densely packed designs where board space is limited.
