Grounded AC-to-DC plug-in power supply?

Does Digi-Key have any AC-to-DC grounded plug-in power supplies? We can use 6VDC, 9VDC, or 12VDC output, 100mA or more. A 5.5mm x 2.1mm plug would be good.

The problem is that we get humming from the microphones in Koss headsets (but not Logitek and Sennheiser headsets).

Hello,

It looks like all the AC/DC supplies including wall warts and desktop style we have is stock are not grounded. This is what we carry inlink below.

I’m actually finding a number of devices that appear to meet the requested criteria here. While most such products do indeed use a 2-conductor input plug, those with 3 can be identified on the basis of the input connector used

Thanks. Can I make a suggestion? Can you add an option-select column for grounded? Trying to identify grounded AC adapters by electrical plug isn’t easy.

Hi,

I submitted your suggestion but please be aware that I cannot guarantee if it will be implemented.
Take care and stay well.
