Trafo question...

[buhler]

hey guys, this shop is right down the road from my house and i thought i might give this transformer a shot.  i am pretty intimidated by the PSU part of this build. :-[  anyhow, will this transformer work?  thanks.

[edit] looking at the pictures, i'd probably actually want this one...?

The second one is 24V centre-tapped, which is likely ideal for + 12V and - 12V. 

Since you're wiring mains-level AC to the other side, take precautions!  Use some heat-shrinkable tubing to go over those connections so that you don't give yourself a nasty jolt when you're poking around with the power on.  A fuse inside your enclosure would probably be a good idea here.  Anything from a 1 amp to 5 amp AGC fuse will protect you from a dead short.

thanks neb!  i'll be back with fuse questions later.  going to buy that transformer!

Good price, too.

don't give yourself a nasty jolt when you're poking around with the power on.

Better still, turn the mains off when you're anywhere near it ;)

Where's the fun in that?

True. Try testing the mains power on your tongue, or kissing soldering irons, for super fun good times.
