Hi Richard,

I have heard that Astron is very tight-lipped about tech info for their
power supplies. It isn't just Astron, however. I have a Magnetech RV
converter (a switching supply used to provide 12VDC for an RV), which is
rated at 55A @ 12V, which I was interested in using as a shack power
supply. I emailed the company, and the only thing they told me about it
was that that it would work OK without a constant load on the supply,
and that all schematics, parts lists, and circuit descriptions were
"proprietary information"!

All help appreciated.
