Hi Pete, That would be me that mentioned opto couplers that have zero crossing capability. Do a google for "zero crossing opto coupler" and you will get a bunch of hits. Then you got to filter all the crap to find the worthwhile stuff. Each have their own particular advantages and disadvantages, so it will take some thought as to use.
A number of manufacturers make a variety of opto couplers with different capabilities. Here is the link to one such device, even though this may not be the way to go. http://www.fairchildsemi.com/ds/MO/MOC3063-M.pdf There are many ways to skin the cat and this is just one part. It does require some external parts to use it, as would all opto couplers. BUT, before you get carried away, here is a worthwhile article to read about a descrete circuit. The important thing is to read his description about how the circuit works and why he chose this particular circuit layout. It is quite interesting ! http://www.dextrel.net/diyzerocrosser.htm Bill....WB6BNQ Pete Lancashire wrote: > Someone mentioned a modern chip for detecting zero crossing. > > I seem to have deleted it > > Anyone have it ? > > -pete > > _______________________________________________ > time-nuts mailing list -- [email protected] > To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
