[sdiy] Power Supply questionsss

[Theo]

Current regulated PSU are mainly used for testing and repair.
It is a way to make sure a circuit with a bug doesn't get fried by drawing a
large (too much) current.

Don't know for sure but there may also be some industrial high power
applications for current regulated PSUs.
Ping Harry?, any shocking/sparkling revelations on the subject?
