Industry: Medical
Application: Patient Monitor
Power Solution: NGE12I05
 
The MEAN WELL NGE12I05 is a compact, medical-grade 12W interchangeable-plug AC-DC adaptor suitable for portable medical devices requiring global certification and safe, low-leakage operation. It supports wide input 80–264Vac and features an ultra-slim 28mm design for easy mobility. The unit is approved for IEC/EN/UL 60601-1 medical safety standards, ensuring compliance for patient-contact and home-care medical equipment.
 
With interchangeable AC plug options, the NGE12I05 is ideal for mobile bedside monitors used across regions. To meet the customer’s non-standard polarity requirement, MEAN WELL provided a DC connector modification service—reversing the barrel polarity to center-negative, ensuring seamless and safe integration into the medical monitor design.

 
CUSTOMER PAIN POINTS:
 

• Medical safety compliance required: The medical monitor must be powered only by certified medical-grade adaptors that meet IEC/ES/EN60601-1 safety and low leakage current requirements for patient-environment usage.

• Portable design & regional use: The monitor is frequently moved between rooms and facilities, requiring a lightweight, wall-mount adaptor with interchangeable AC plugs rather than a built-in PSU.

• Non-standard DC polarity: Standard barrel connectors are center-positive; however, the customer’s system requires center-negative wiring. A customized DC plug/assembly is needed to prevent polarity mismatch and equipment damage.

POWER SOLUTION:
 

• Medical-grade adaptor selection: NGE12I05 featuring IEC/EN/UL 60601-1 / -1-11 medical approvals and extremely low leakage current (<100µA), suitable for patient-connected use and home-healthcare environments.

• Portable and global-compatible design: The I-type version includes interchangeable AC plugs (EU/US/UK/AU/CN/KR/IN), supporting international deployment and convenient mobility with the monitor.

• Reverse polarity DC plug customization: MEAN WELL provided a connector modification service to reverse barrel polarity to center-negative, ensuring the adaptor output matches the monitor’s unique power input requirement. This prevents reverse-connection risk and eliminates the need for the customer to modify cables in-house—enhancing safety and reliability.

 
CONCLUSION:
 
The NGE12I05 delivered a compact, safe, and portable medical-grade power solution tailored for mobile patient monitors. Its 60601-1/60601-1-11 compliance, ultra-low leakage current, interchangeable plugs, and 3-year warranty ensured regulatory readiness and flexible deployment. Through custom DC connector modification, MEAN WELL supplied a center-negative barrel plug configuration, fully aligned with the customer’s design. The result is a safe, plug-and-play, global medical power solution supporting mobility, compliance, and long-term reliability.
