Is there a way I can simulate turning a variac from 0-100%?

Is something like this good enough? Click it and try the simulation:

It doesn't simulate the transformer itself, but it does produce a 60 Hz sine wave which is growing in amplitude 0-100% over the course of 1 second. It accomplishes this using a multiplier.

You could then replace V2 with some other signal that describes your 0-100% ramp. For example, if you want it to be 0-100% over 5 seconds, you could set V2's value to be PWL(0,0,5,1).
