Why Medical Device Manufacturers Choose Certified Medical Power Adapters

Risks of Using Non-Medical Power Adapters
01
Fails IEC 60601 compliance requirements
Standard power adapters are not designed for medical safety standards, leading to certification failure and project delays.
02
Excessive leakage current risks patient safety
Uncontrolled leakage current may pose serious risks in patient-connected applications.
03
Unstable performance across batches
Consumer-grade power supplies lack strict consistency control, increasing failure risk in critical environments.
04
Repeated testing and certification costs
Non-certified designs require re-evaluation, wasting time and increasing compliance costs.
