xylotec xfrmr was Re: Don't give up!!!

John,

It really has gotten reasonable, hasn't it?...

One note, the Xylotec board may not like that 24voltAC transformer!

When rectified and filtered, it will likely put out about 34VDC; and
the limit for the chips used by Jeff is 35VDC. A bit close...

Better to find an 16-21 A/C volt xfrmr, for a max supply of 30VDC.
This is what Jeff recommends, voltage wise, for his xylotec boards.

Hope this helps,

Ballendo
