[sdiy] Hooking up a Power-One unit

[David G. Dixon]

John,

The terminals are little solid cylinders, about 1 cm high and maybe 2.5 cm
in diameter, with one little ring or flange about halfway up and another at
the top.  They look like something is supposed to slide over them, but I
don't know what.  Also, there are seven of them, labelled as follows:

-OUT   -S   +S   COM   -S   +S   +OUT
            -------------

I'm presuming that one uses the -OUT, +OUT, and COM terminals, and the S
terminals are for remote sensing.  I take it the latter are unnecessary
unless very long power leads are used. (?)

I've had a thorough look at the datasheet, and no guidance is given there
for these terminals either.

While I've got your attention, perhaps you can tell me about the standard
way to connect the output terminals to the distribution board.  I'm looking
at the picture of the MOTM-900 (http://www.synthtech.com/motm900.html, click
embedded picture) but I can't make out what the connectors are either on the
board or on the supply terminals.  I'm guessing the terminals on the board
are flat slip-on tongues like those on the Power-One transformer.  I'll have
to look for those at my friendly neighborhood electronics store.

The Power-One output terminals are shown quite clearly in the picture, and
those which are connected appear to have heat shrink tubing on them, but I
don't know how the leads are actually attached.

Any help much appreciated!
Dave
