Hi guys,

I have a laminator that I would like to make adjustable (and more accurate) temperature wise. The unit runs off 240VAC. The heater is controlled using a thermostat switch, but the AC is half wave rectified.
I would like to replace the thermostat switch with a SSR, but am unsure if this will correctly switch the half wave power? Does anyone here know if this is possible or propose a better solution?

Cheers
Simon

How many watts is the laminator' heater? If 500W or less (mine is 370W) a simple light dimmer will do the trick HOWEVER
make sure that whatever you are controlling does not also control anything else or it may stop working.

SSR is simple and rugged but since it's already DC can use a FET to reduce the price.
