MOTM

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.

Oops...if you're interested at all in the last link I sent, remove the ).

their main page, turn your speakers down first, there is loud static.

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.

Thanks for the suggestions. This is exactly what I was looking for.
