3046 BURNOUT

[Augusto Pinoche]

Exactly, in the oven cirquit you always
have a current limiting resistor, this resistor
limits the current drawn thru the oven and
the current source, in this case your regulator.

Nor the oven or the regulator should Burn out
if it does you have to redesign your oven
or current supply since there is  somthing faulty.

AP

There is no need to drive the oven above
50 degreees celsius
