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 MDD01L-12N typically used for?

The MDD01L-12N is a 1W SIP7 DC-DC converter designed for low-power isolated voltage conversion in compact equipment. It is a practical fit for medical, industrial, and control-board applications where reinforced isolation, small size, and a regulated ±12V output are important.

Is the MDD01L-12N suitable for medical or safety-sensitive equipment?

Yes. The product data lists medical safety approval to IEC60601-1 with 1xMOPP/2xMOOP and a low patient leakage current below 2μA. It also lists safety certifications including CB, UL, EAC, CE, and UKCA.

What are the key output and protection specs for the MDD01L-12N?

This model is a 1W converter with a ±12V output and a rated current of 31mA. The series data also lists continuous short-circuit protection and overload shutdown with automatic recovery, which supports fault tolerance in low-power designs.

Can the MDD01L-12N operate in demanding temperature conditions?

The specified operating temperature range is -40°C to +95°C. That wide range makes it suitable for equipment exposed to cold starts or elevated internal temperatures, provided the full system stays within its thermal limits.

What makes the MDD01L-12N different from a basic low-power DC-DC converter?

A key differentiator is its 6KVDC input-to-output isolation with reinforced insulation in a compact SIP7 package. The listed medical approvals, low leakage current, continuous short-circuit protection, and 3-year warranty make it more specialized than a generic low-cost converter.
