hey again! can someone show me a schematic of how to do this? thanks!

Re: Help! How to bring 14.3V AC down to 12V AC?
Generally, the only way to convert one AC voltage to another is through a transformer. You aren't likely to find one with that particular ratio. What is your source, and what is your application?

Well.. I was pretty sure that a transformer was the only way to solve this... but I had a littel hope... Hahaha. I guess I'll try to find another transformer and try again from there... thanks anyway Artie! You've been a great help!

Re: Help! How to bring 14.3V AC down to 12V AC?
Lets say you have a transformer that designed to run a pedal at 12 volts. If you measure its output when it isn't plugged into the pedal, it may well read 14 - 16 volts. Does the transformer you're using have a current rating on it? Like sometimes, they'll say 600ma, or 1200ma. That type of thing. Is this a wall-wart type of thing?
Is this a home-built system, or a commercial product? Was this transformer made for this particular system?

Re: Help! How to bring 14.3V AC down to 12V AC?
You could put a 10 ohm resistor across its output, and then measure it. The problem is, you need a really big, expensive one. Like in the 20 watt range. Even then, you'ld only want power on it for a moment or two. Just long enough to measure the output.
Really though, your 14.3 should be fine for a 12.6 volt project. The transformer will drop a little bit with a load.
Then again . . . I don't really want to tell you to hook A to B without knowing better what you're doing.
Long distance troubleshooting can get one of us fried. Probably be you.

You're probably safe, but it's so hard to say without knowing exactly what you're doing. One and a half volts isn't a big deal in many circuits, but then again, I'm not sure what your circuit is.

Use a 12v light bulb for a load. Get a 12v halogen lamp or a tail light replacement bulb at any auto parts storeLast edited by Chaos; 02-27-2006, 08:25 PM.THE LOST ART OF BEING STOIC
1. Quit your whining.
2. Quit your crying.
3. Suck it up.
If in doubt, ask yourself: What would Clint do?
