I need a 25mm x 30mm 120V 200 watt band heater.
Unfortunately, the only 25mm x 30mm 120V band heaters I have found are 300 watt.
What sort of circuit could I construct or purchase that could regulate the current flowing through a large heating element like that?
Ideally looking for something off the shelf.
I'm used to limiting current (say, through an LED) with a small resistor. I have no clue how to design for something high current like this.
Doesn't have to be adjustable, literally all I want to do is ensure the heating element dissipates 200 watts, not 300. I'm guessing the element is resistive.
My power supply is 250 watts, so I'm not trying to dissipate any power in the control circuit.
