The PCB will be around 45cm long and 20cm height. Measurements are taken into account to fit properly in my dedicated electrical closet. This can be changed as we go along the road of drawing this beauty. Rem
ember that it's not me doing this it's actually my friend. I just give some useful tips ;-)We also increased the maximum power of each dimmer to around 1000W. The maximum power is bottlenecked by the coils against disturbanty because the triac can have 3000W easily. This implies that the central power lines on the PCB will be about 1 cm width (see on the picture the big blue one) which can take 16 amps so pretty secure. We will also try to make it on a simple double layer to reduce the PCB cost. As you can see all the power (AC) connections are grouped on the right of the board. Our intention is to group the DC connections on the left. This makes the board very suitable for connecting it and moreover the sensitive signals are proper separated from the manes. I took black as the color and the printed tekst will be white. A pitty yellow is not available tough. The purpose is to mount the board with plastic or Teflon distance tubes using 4 or 5 mm thread inside and some nuts. Because of the precense of highvoltage on the board we must make a shield over it to avoid direct contact. That we 'll do using a transparant plexy glass which we are going to mount above the PCB using the same threads and distance tubes so it becomes very safe and nice to look at. I'll continue in this blog letting you see the evolution of the board with some extra guided words.
