Hey there fellow freaks.
Recently a client came to me and was wondering if my company would be interested in manufacturing some simple 4 channel light chasers 24V / 200VA total load. I said I would get back to him.
Anyway, I've looked into it a little but am a little confused by the vast array of Triacs that are out there these days. Seems every Triac manufacturer is claiming their triacs are the best.
I was thinking i could manufacture this chaser using a ATMEGA8 solution that is non-isolated using 'logic level' triacs and using a simple zero crossing detector using the ATMEGA8s comparator, that way i could keep the component count low. Ideally this board would be mass manufactured so a nice SMT based solution is what i envisage, if the board fails it would be a throw away afair.
I just want to throw this idea out here to get some advice/ tips / feedback before I commit to an order of a handfull of triacs, etc.
I searched the forum here for threads dealing with Logic Level triacs and didn't find any, so perhaps this can be a good starting point for some discussion.
Look foward to some feedback.
