Why not build the amp out of 48 volt transistors? I have a dozen 300 watt 48 volt power transistors that I have been saving for such a project. This should reduce the current requirements and hopeful
There's been a great deal of speculation and advice on here regarding this, but in reality, a simple answer to the simple question has been provided. There are absolutely 12V, 120A "off the shelf" po
Uh.... Did not know that! Curiously, How much does one of these 120 amp switchers cost and are they RF quiet? Phil W2GE There's been a great deal of speculation and advice on here regarding this, but
they run about a dollar per Watt. I would say they are _very_ RF quiet, since their primary applications are powering large telecommunications systems which need to meet not only FCC Part 15 Class (
Quiet? Not the FCC Class B telecom units I've been playing with. These beasts put out relatively low noise differentially between output V and its ground but put out a lot of noise "common mode" betw
Hi Jeff. I had the same experience buying a CE certified supply. Compliance emissions testing must have been done without any wire attached to the output leads! As soon a a wire was applied , it sang
Not only power supplies give problems.........some years ago, we were involved with Part 15 Type Approval: the equipment was to work with a laptop, and a very well known Japanese make of laptop radia
