## Variac

 Is there a way I can simulate turning a variac from 0-100%? by spudwheelie December 06, 2020 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). by mrobbins December 07, 2020 Thank you! by spudwheelie December 09, 2020
