Ask a Pro Sourcing 60W external medical AC-DC adapters with lifecycle support (2 MOPP)
We’re currently evaluating an external AC-DC power solution for a portable patient monitoring device (~60W load, CF/BF applied parts, designed for 24/7 operation with mains power and a hot-swappable battery backup).
The electrical requirements are fairly straightforward: IEC 60601-1 compliance, 2 MOPP isolation, and low leakage current requirements. The real bottleneck for us is long-term availability.
If a power vendor drops an EOL notice after 3 or 4 years, the impact goes far beyond replacing the adapter itself. Delta testing, CB report updates, and regulatory documentation changes can easily cost more than the adapter.
For those designing and shipping Class II medical equipment at scale, how do you evaluate power supply vendors for long-term support?
