wil1948:

That is a PWM controller, yes. I do not know your application but if you want to control temprature and voltage to control condensation (as I had planned and mentioned in my post) then that module won't be enough.

I think it is just a adjustable PWM controller, has a timer IC, and a transistor. What it does is lower or raise the voltage by turning the knob. There is no automation. It is WAY better than a simple adjustable resistor in series.

Be warned that they have mentioned 15amps max and pelts require much more constant current.
