immediate current overload foldback. Seems to be happy to sit that way, but of
course you don't get any output voltage.

Since I’m the one who started this thread, I think it is incumbent upon me to
let the collective masses know how I am proceeding…
To date, I have added additional filter caps (0.1 µf disc caps) to the SCR
(GATE to GND) and across the output of the supply. I have already affixed
ferrites to
tching supplies.
Let's hope Skip comes aboard here. I know he's
had experience with these units.

Clip the purple wire going to the crowbar.
The crowbar in the Astron is one of the most messed up deals ever.
Astron also makes and auto reset kit for the crowbar.
Or better yet, go find a Mastr II 35 amp supply and be done with it.

Thanks to all who have offered suggestions - however "sarcastic" - about
remedying this situation. They all merit consideration, and I will certainly
do so... and will post my results!

Hi, Bob. Long time, no chat!
The Astron P/S only supplies the PA - all other items in the rack have their
own power supplies, but I can still see where I may have exceeded the

I've had DMMs also go nuts at my site too. Luckily the Astron supply hasn't had
that problem yet.
The fuse usually blows when something catastrophic happens. One such thing is
when the output voltage goes too high a

For t

This cuts the current consumption in half and they can be run with switching
supplies.
Let's hope Skip comes aboard here. I know he's had experience with these units.

I know there has been some discussion on one the list regarding Astron Power
supplies. Unfortunately, searching hasn't revealed what I am looking for,
so I pose my query here and apologize in advance if this was a subject that
was discussed at length in the past. I
