 Posted: Mon Jan 02, 2006 7:50 am Post subject: D25 Steering Diode Question ? |
 |
|
Anyone? Just need a little learning experience. In the Connection, Bob says
you can just cut off two of the tabs on the D25 and use the + and one
adjacent to the +. It appears that either of the poles adjacent to the +
will work fine. Now, on the diagram that came with the D25 from B&C, they
show a configuration as a steering diode between the Main and E-Bus and they
want you to connect both of the poles adjacent to + in a kind of wishbone
scenario instead of just one pole.
I think that there is a diode on each pole but what would be the benefit of
connecting it this way. Does it carry more current, provide redundancy,
etc. ?? Why or why not use this configuration?
Thanks for the help.

Correct

this works too.

You'll get a slightly lower voltage drop but not significantly
lower. You can wire multiple diodes in parallel but don't depend
on this technique to "double" current rating of the steering diode.

You already got your official answer from Bob, so this is just
a bonus confirmation. Yes, you have 2 diodes that you can use
in parallel, with a common output. You won't get a lot more current
carrying, because it's still just coming out one terminal, but
you can use both diodes if you're so inclined. I just wired mine
yesterday and used both.
I'm also hoping that Eric gets a good mounting kit for his
schottky diode, as I'd really like to use that one instead
if possible.

Tim, Bob, thanks, just what I needed to know.

I agree. The down side to Eric's Schottkey diode is that it is not as
friendly in mounting with fused buses as the D25. I am toying with the idea
of gluing my Schottkey to a piece of angle aluminum to isolate it and mount
it to the frame using plastic screws. Not sue if the glue will handle the
heat however. I am using fused buses FWIW. A good heat sink with isolation
mounting would be very nice support for Eric in my opinion.
