It controls the Triacs (lets talk single phase -- the black-and-yellow boxes) which lose quite a few watts (therefore the grilled enclosure). The blue "on/off" square wave is just the average power run through the triac, which modulates the power by clipping the sine wave. If you really, really wanted to, you could modulate the triac with a triangular pattern and you would get the wavy line. > The only problem is that the cable between the control box and the > device contains "secrets".

But what it is DOESN'T FURGING MATTER.
