I need to replace a DC adapter for an old NAS that was lost to a power spike but I'm having a hard time identifying exactly the kind of connector.
This is the connector on the back of the NAS:
I have this universal adapter kit that I use temporarily:
And after testing a few plugs I discovered this is the one I need:
The plug has the following specifications:
- outer diameter: 5.5 mm
- inner diameter: 3.0 mm
- no pin inside the plug (the pin is in the NAS connector)
I don't want to keep using the kit and need to find a definitive replacement. However, I'm having a hard time finding one with these exact specs.
I would like to know:
- Is this a standard size?
- Is there an IEC-like code for it?
Any additional information is appreciated.
