I have a dell 65w power adapter that came with my new laptop (usb-c plug). I’m only concerned with the output power. It seems to list 4 voltages, 5vdc, 9vdc, 15vdc and 20vdc (top pic). Am I reading this correctly? Anyone familiar with power adapters? Or better yet, has taken one apart?
The reason for my questions is… Found these ferrites in a box a couple days ago (bottom). It’s a field modification for the patient table of a catscan. Myself and another guy built the first one of these to ‘clean’ the power feeds to patient table dc drive motors. Our 'fix' was redesigned/refined and then sent to the field as an FMI. Sadly, I don’t remember the specific details, just the general purpose. I have no part #’s or specs but clearly they are rated for higher current than the 3amps from the laptop adapter.
I’m thinking about how to use them now. Possibly to clean the dc power for my new laptop (or anything else I can think of). Do we have any ferrite experts in our group?
