Please log in for more thread options I believe that most of the sealed supplies have thermal protection built
in. Hopefully, they all use ones that reset when the unit cools.
I have a professional electronic flash with an AC supply that has a
"thermal protection circuit" that uses low temperature solder to hold a
spring contact in place. When the unit overheats, the solder melts and
the spring switch opens up and shuts off the power supply. It's not
consumer repairable.
My most recent trip to the local computer superstore located a third
party ac/dc/aircraft supply that was at least 100w and may have been
120w. Unfortunately, if my memory is correct, the dc aircraft supply at
the seats isn't rated to supply that much power.
