Product information

Description

The MEAN WELL MDD01N-12 is a PCB-mount DC-DC medical converter designed for low-power applications. It accepts a nominal input range of 21.6–26.4 V DC and provides isolated dual outputs of ±12 V at ±0.042 A. The module is supplied in a SIP through-hole package and includes reinforced isolation (2xMOPP) suitable for medical equipment designs requiring patient safety separation.

Advantages

The converter offers compact PCB mounting in a SIP through-hole form factor, providing dual isolated outputs with low power consumption and compliance with medical isolation requirements (2xMOPP). Its narrow input range and steady dual ±12 V outputs make it suitable for small signal circuits and isolated power domains on medical PCBs.

Suitable for

  • Low-power medical electronic modules requiring isolated dual rails
  • Signal conditioning, sensors, and low-current analog circuitry
  • PCB-mounted designs where SIP through-hole packaging is preferred

When it may not be suitable

This module delivers only 1 W total and ±0.042 A per rail, so it is not suitable for applications needing higher output current or significant power. The input is limited to 21.6–26.4 V DC; systems with widely varying or lower input voltages will require a different converter or a preceding regulator.

Key specifications

  • Function: DC-DC converter (medical)
  • Mounting: SIP through-hole PCB mount
  • Input voltage: 21.6–26.4 V DC
  • Output voltages: ±12 V DC
  • Output current: ±0.042 A per rail
  • Output power: 1 W
  • Isolation: reinforced isolation (2xMOPP)

How to use

Solder the SIP through-hole pins to the PCB following the manufacturer’s recommended footprint and maintain required creepage and clearance distances for medical isolation. Provide the specified 21.6–26.4 V DC input and verify polarity before powering. Route output traces and grounding to preserve isolation and minimize noise; follow board layout guidelines for isolated converters and include appropriate input filtering if needed.

What to consider before purchase

  • Verify that ±12 V at ±0.042 A and 1 W total meet your load requirements
  • Confirm your system supplies a stable 21.6–26.4 V DC input
  • Ensure SIP through-hole mounting and PCB space suit your design
  • Check required medical isolation levels and regulatory testing for your end product

Usage recommendations

Use this converter for low-current, isolated dual-rail needs on medical PCBs; keep trace lengths short, separate analog and digital grounds where appropriate, and include input decoupling to maintain stable operation.
