Can two inputs make an isolation transformer?
<< < (4/6) > >>
scuzzyTerminator:
To clarify my intents, this was a case of grabbing something before they are gone and then figuring out what I got. Now these look like they are nice isolation transformers so I went back and bought two more. The last two. Couldn't just leave them there.

I also picked up these two. Labels are good. CJLTT.

Thanks again, everyone.

My post above had a link to the full specs and schematic??  |O

Thanks. I went back to the store today and found what I think is the correct schematic. Exactly the same but with a ground shield.

Those certainly look like they are supposed to depict 1:1 windings.

There are several different types of insulation:

Functional: can only withstand enough voltage for normal operation. Failure of such insulation will not pose a shock hazard.

Basic: used between an earthed enclosure and live parts or a non-earthed enclosure and some live parts with another layer of basic insulation in between.

Reinforced or double: used between a non-earthed enclosure and live parts.

Functional insulation is the bare minimum required to allow the device to work.

Basic insulation needs to be significantly over-rated, because its failure can result in electrical shock, although not so much as reinforced insulation, as there's  enclosure is earthed or has another layer of basic insulation, offering more protect.

Reinforced insulation needs to be twice as good as basic insulation, because there's only one layer between it and the user.

why medical isolation transformer use torroidal construction?  :palm:

in 80`th all medical trs has primary and secondary coils at DIFFERENT bobbins to eliminate parasitic capasitance
Zero999:
Why not use a toroidal construction for a medical grade isolation transformer?

There's an earthed screen between the primary and secondary, which both offers additional protection and prevents capacitive coupling between he secondary and primary windings.
