Power adapter MEAN WELL MDD02N-15 2 W 15 V 21.6-26.4 V

The MEAN WELL MDD02N-15 is a PCB-mount DC‑DC medical converter designed for applications that require isolated dual outputs. It accepts an input voltage between 21.6 and 26.4 Vdc and provides dual ±15 Vdc outputs with a rated current of ±0.067 A per rail. The module is supplied in an SIP through-hole package and meets 2×MOPP isolation requirements for medical use. It is RoHS compliant.

Advantages

This DC‑DC medical converter offers compact PCB mounting in an SIP through‑hole format, low power consumption at 2 W total, and fully isolated dual outputs of ±15 Vdc suitable for symmetric supply rails. Compliance with 2×MOPP provides safety isolation for patient-connected equipment, and RoHS conformity ensures reduced hazardous substances.

Suitable for

• Medical instrumentation requiring isolated dual supplies
• Pocket or embedded devices on PCBs with limited space
• Signal conditioning and sensor interface circuits needing ±15 V rails
• Applications that require compliance with medical isolation (2×MOPP)

How to use

Mount the MDD02N-15 onto the application PCB using the SIP through‑hole pins, observing correct polarity for the input supply of 21.6–26.4 Vdc. Provide proper input decoupling and follow the manufacturer's recommended PCB layout for isolation creepage and clearance to maintain 2×MOPP performance. Connect the ±15 Vdc outputs to the load, ensuring the total output current does not exceed ±0.067 A per rail and the combined power remains within the 2 W rating.

Recommendations

Ensure adequate thermal management and maintain required creepage/clearance distances on the PCB to preserve medical isolation. Verify that the connected circuitry does not draw more than the rated current, and follow applicable medical safety standards when integrating the module into patient-connected equipment.
