A problem is, for the lower right part, that it was intended for 120 volts, while I want to run that part on 220 volts. Now my knowlegde on circuit analysis is not good enough to figure out if I would need different resisters now. Any one knowlegable enough to tell me something about that? How do you analyse a circuit with a triac? What kind of voltages and currents will there be in the lower right part of the circuit (with for example a 200 watt load)?
I wonder why you are switching the line side instead of the neutral side
I prefer to keep away from the hot side as much as possible
as well as possibly different resistors, you need to check that the triac can handle the higher voltages
once you've done that - and possibly selected another triac, you can then decide how to drive it
Well in the Netherlands you can plug in a power cord in both directions in the socket, so you never know which one is neutral, and which one is the power. So does it still matter where you put the load then?
How do you calculate then what resistors would be appropriate, and much power they should be ale to handle? I do know basic rules like I=V/R etc. But not sure how to analyse the triac stuff.
that triac looks man enough for the job
it doesn't really matter which side the load is
just don't touch any of those parts!
not sure I can help with the triac driving
but there is another bit of circuit connected to an opto-coupler I guess
it needs a suitable resistor too
that's easier, just double whatever was there before
