#146224 - zero crossing switch Responding to: ???'s previous message |
Would a properly designed SCR circuit to replace the relay fix this problem?
there are oodles and bunches of zero crossing switch modules out there, I doubt you can do better (technically or economically) than buying one. for reference, here is a type grabbed at random from the digikey catalog http://pewa.panasonic.com/pcsd/prod...at/aqr.pdf Erik |
