EL Inverters - Descriptions+questions!

Postby V`cent » Thu May 03, 2012 7:42 pm

Hey, in looking trough your EL inverters for a costume/festival project i found a thing that bothered me :
This Inverter (12V #448) 's descriptions says that it can power 1M of LED tape (100SQ/CM), but so does this one(4xAAA#564).
While it's obvious that the 4xAAA will die a lot sooner than the 12V one (if using the 8XAA battery holder),
my question is why the 12V one can't be used for ex 1.5 or 2M of EL tape?
Is it a heat dissipation issue, or is the part simply not suitable for "heavier" lifting?

If given enough power to draw from, would it die or would it soldier on?
Taken from the description:
It is also more powerful, and can drive twice as much EL! ... [12V EL Inverter]

+
It's got twice the power of the pocket inverter [12V EL Inverter]

Indeed, it says it can power ~6M of High Power EL wire vs. the pocket inverters ~3-4M.
Yet they can both only power 1M of EL tape? :(

This is mostly interesting since carrying one or two 8XAA battery holders isn't too bad, but running around with 3-4 of them would very quickly start to suck :lol:
(2M for front +2M for back, at the very least.. probably more )

the 12V inverter could theoretically run 150 sq cm of EL panel but since our tape and panels come in 100 cm sections it makes more sense to use one per. Otherwise you would have to cut the tape in half per inverter.

BTW you CANNOT parallel inverters, EACH inverter much drive its own EL panel/tape!

Yeah, they would kill each other :)

I guess ill go with 2-4 12V inverters then(all running for themselves, no worries! :D), and cutting & splicing tape to make it look like more.. Might throw in some wire while I'm at it ^^
Anyways, thank you for the quick reply :)
Next years project will be sequencing the different strips.. Aww yeah.. Anyways, will upload photo's to the AdaFlickr pool when done!
