Yeah, i'm an electrical engineer student (if that's the right term) so i do know a bit of these things. Just can't be arsed to calculate the power usage on 230V and using the lowest temp setting from the switch... Unless required to :P Seems like that i do.
Did the coil burn whilst using the LOW-setting?
or did you use the highest temp setting for five times, and finally it blew?
Just in short, correct me if i'm wrong (which i think i am
it's designed to be used on 120VAC 60Hz, so:
The coil works at maximum of 750W -> 750W / 120V = 6,25A
It will take 6,25A current at max.
If i'd use the default potentiometer on the 230V net, and set it to max temp, it would be going on 6,25A * 230V -> 1437,5W power!
No way! that WILL blow the thing in a blink!
So, i want it to draw a maximum current of X, so that it will (at max) use 750W power:
If x * 230V = 750W, then x = 3,26A
So i want it to draw 3,26A max from the network.
If I = 3,26A and U = 230V, then R is... Yeah, R = U / I, R = 70,55ohm
So if i find a potentiometer (or just a plain resistor), could it work? i know that the resistor would need to have insane maximum power durability, but just in theory, it is...
