I do this stuff for a living, and have over 30 years experience. In
that time I have developed methods and instincts for evaluating vendors
(after you are burned a few times you get to be really careful). First,
I have been using Datel products for 30+ years and have a real comfort
zone with them. Second, I read the data sheet (which you can also do).
Except that you can't do that with Dimension Engineering because there
isn't one! Now, that is a major red flag in my book (maybe not yours).
And don't assume that just because somebody is selling something that
it works as advertised. That is, perhaps, the silliest thing you said.

If you want a MIL SPEC qualified dc-dc, they are available too. Try
Vicor. You'll just pay A LOT more. The Datel unit is known as COTS (for
commercial off the shelf).

I said that it looks like a hobbyist product, and it does. Since when
is that *DISSING* anybody? Furthermore, what I was saying was that it
was MADE by hobbyists. That are lots of well designed commercial
products FOR hobbyists, but that is not the situation here.

I stand by my original comments and would recommend for the Datel unit
and strongly against the Dimension Engineering. You, of course, are
entitled to your own opinion.
