Ray, we use Samlex on our oyster farm. We have a 24 Volt system which
powers pumps and an oyster sorter. The sorter takes 240 and transforms
to 208. We have not had any issues except that we sometimes have to
turn off the inverter and then back on to energize. The GFI is also a
little cranky on these but that could be because of the conditions we
are working in. Chris

Hi All;
I've just had an inquiry on building a portable sound stage and
recording setup. Traditionally we've always used Exeltech, as they've
had the cleanest output, with background buzz on tube amps being lower
than grid power. Modsine were horrible, Old Trace SWs were pretty
intolerable, Magnum's were usable, but still noticeably more buzz than
grid. I think THD is roughly associated with the background buzz, but
there might be certain harmonics that are particularly problematic. I
haven't gotten into looking at the separate harmonics relative to what
induces the most noise in these old vacuum tube circuits.
This is a 48 v application that also needs a built in charger with
transfer switching. Exeltech does not appear to have anything in that
department. Any other choices? How are Samlex?
As always, thanks in advance for your time and expertise,
