MOTM

Ben, the power supply you need will be significantly more complicated than
the one that could connect with a barrel connector.  The power supply you
seek will be a 4 wire connector.  You are probably not going to find a cheap
computer style switching supply because most of those have +/- 12 volts and
+5.

If you want a quality linear supply to do the job, and have some left over
room for loadability (maybe to power a few MOTM modules), This is the
smallest one I found to do the job:

Mouser catalog: page 652, triple output, International Power 597-TAA-16W
$57.75

Marlin Jones www.mpja.com has the same supply listed as part number IHTAA16W
for $51.97

You may find one of lower loadability that does not have 5 volts.  But, this
is the smallest one I found with 5 volts. Its loadabilty is 2A @ 5V,  400ma
@ -15 and 400 ma @ +15.  One catalog quotes 12 volt.  But, this type of
supply has an adjustable output that can be set for 12 or 15 volts.

You could always power the +/-15 volts from you MOTM supply and hack in a
cheap switching supply for the +5 volts.  But, given your self-described
electronics experience, perhaps that might not be a good plan.

Subject: [motm] OT power supply question...seeking a recommendation


Hi all,

Sorry for the OT post, but I figured there are a lot of people that peruse
electronics supply catalogs here...
I recently purchased a video synthesizer, an A2V audio-to-video convertor
(http://www.audiovisualizers.com/library/store/a2v/a2v.htm). It is fully
assembled except it needs an enclosure, needs jacks wired up and a power
supply.
Can anyone recommend a good power supply for this application? I prefer a
wall-wart with a barrel connector and a matching inlet I can put on the back
of the enclosure, then wire the inlet to the board. According to the manual,
the specs I need are:

+5V 200mA max
+15V 100mA max
-15V 100mA max

Does anyone have any recommendations? I was doing a search for this earlier
but turned up a ton of info and a lot of it was Greek to me, so to speak. I
know how to solder but am otherwise an electronics idiot; yes, I buy all my
MOTM modules assembled...
Thanks in advance.
