Subject: [Amps] rectifier diode modules
I'm looking for suggestions for a source of diode blocks to use in a couple
of HV power supplies. I'm using a bridge rectifier and would like to have
8KV-10KV PRV per block. The power supply will be rated at 2A DC, so I'd like
at least 1A max continuous rating per block.
I have some blocks scavenged from an old ARD-230C amplifier rated at
8IV/750mA. I ran one for 45min at an amp with no problems, so I can probably
make do with those if I can't find any others. They're made by a company I
never heard of, but are very attractive.
Henry Radio sells "half-bridges" which are rated at 15KV/1.5A, but that is
7.5KV per leg and I'd like a bit more.
This is all about cosmetics, by the way. I know I can string a bunch of
e.g., 1N5408 diodes, but I prefer the elegance of blocks.
Tnx,
### http://www.rfparts.com/hvrect.html scroll from top to bottom, and
they have
everything u need. The single phase bridge assy...at the very bottom, is used
in broadcast TX
and is very similar to the one dahl used to make. They both use 6A10's with a
mov across each diode.
#51014/51050.
## If you don't want to blow em up, then install a HV fuse between xfmr sec
and input to diode board,
one leg only.
Later... Jim VE7RF.
