Thank you all for your comments. I got some nice ideas.
Perhaps I was not clear enough, possibly due to my skills in English and I got misunderstood.
Triac and Relay are two different things in my design, two different routes in the PCB, two separate circuits. I will drive the load either with...
Thank you Klaus
I agree with your comments and that is why the above mentioned way (with the tranformer and the resistor) would work with the relay output (since my loads are resistive), this is where the idea came from. That is not the case with the triac, the reason why I place the initial...
Hello again,
I would say RMS current but you see, since I do not have the experience on the design of such systems, I am not sure which method would be the easiest to follow. An idea is to place a resistor across the output of the transformer, measure the voltage, multiply with 0.707, get the...
Thank you Klaus and Tony for your feedback and the time you spent for it.
Klaus you are correct with the calculations and I agree with you as regards the precision. But lets say, I do not need precision, lets say I need a "mechanism" that will not allow more than 4-5Amps to pass to the load, no...
Hello all,
I am designing a 230V dimmer using a 12A output triac which I control via a cpu (through optocoupler etc). Is there any way to limit the output current to some 4A (max load about 900W)? Using a fuse before the load would just blow the fuse in case the load needs more current, so it...
