[proportional temperature controller]

Thanks for the consideration. The power consumption was a high estimate. The load will be an oven element in a steel thermally insulated oven.
If i can get a circuit for the controller i will use it for most projects that are a much lower power loading, eg 2.4KW.
Thanks for your reply.
Cheers.

[proportional temperature controller]

I am trying to build a temerature controller to control 240VAC at 10-20 amps. It should control using proportional current to a resistive heater element to maintain a temperature (set between 50 and 300 degrees celsius). Please Help! :-[
