24V, lots of amps .. what kinda setup could manage it?

When I say lots of amps, I mean probably lots .. well .. ok .. maybe
20-30-40 .. something like that .. at a relatively constant 24v ..

What kind of SMPS or other p/s setup would be able to work something like
this?

Thanks in advance :)

**Coupla car batteries works for me. It depends on how long you need the
power.

Nah, looking at creating a system to overcome having a million different
christmas light plugs .. 90% of mine are 24v, rated at varying levels of amp
loads .. FOr the next year I'm planning a computer controlled system, that
would switch on and off sets as needed, would be nice to have a single power
supply for the bulk of them, rather than 20 or so different plug packs ..

Assuming they're all incandescent bulbs you don't need anything more
than a transformer to power them. A 240V 10A outlet should give you
around 80A at 24V (allowing for efficiency losses).

It will be large and heavy and you could probably save money by using
an auto transformer -- but make absolutely sure you understand the
safety implications if you go down that path.

Try looking at www.meanwell.com They have SMPS that will do your job.
Local agents are ADM Instrument Engineering,Computronics and Jaycar.
Check prices from each first.

I hope I am imagining you said auto transformer.

Auto transformers are generally banned in this country (This is AUS
electronics) for consumer use because it is very easy to get the low
voltage part at the high end of the transformer and although it is only
24 volts it could be 200 odd volts above ground and therefore FATAL.
Although there is a wiring convention there is no guarantee that it is
maintained especially thru extension cords.

Shit... whatever will the nanny state ban next!

He might like to use a large Variac instead, with the added benefit of
a built in dimmer control -- assuming he understands the safety
implications of course. :)

**You moron. 240VAC is almost perfectly suited for killing humans. By
comparison, 117VAC is relatively harmless.

**Another moronic suggestion. The insulation on the light strings is rated
for (probably) less than 32VAC. Connecting them to a VaraicT is just plain
dumb.

Auto transformers have been banned for many many years to protect
people like you and the original poster from themselves.
If he knew enough he would not have asked such questions, so all some of
us can do is try to protect him from irresponsible advice from novices
who do not understand the risks.

**Smilies notwithstanding, you are an idiot, for even allowing such words to
be uttered. I am genuinely deeply disturbed to read your posts. You have
absolutely no clue about just how dangerous 240VAC can be, when used on
wires with unsuitable insulation properties. It has NOTHING to do with
getting wires crossed.

I suggest that if you have nothing worthwhile to add to this thread, then
bugger off. Your moronic suggestions will get someone killed.
