YES ...other wise your pot would go up in smoke ...what do you think is in that plastic case that is the SSR VA25 ?...its the bits that make it not go up in smoke ....otherwise we would just be wiring a pot in series with an element :pray:
Funny you should say that ...at work I was playing with a rheostat light bulb and 12 volt power supply , while dimming the light bulb the rheostat was starting to burn my hand ......a 25 watt light bulb and 12 volts .
Now upscale that to 2400watts and 240 volts and explain to me how a 2 watt potentiometer ( rheostat ) is going to disapate all the unwanted power
Hense the controller curcuit :handgestures-thumbupleft:...electronics is there for a reason :think:
