It's still possible a 600w dimmer switch will work in place of the brain box, with the exception it won't shut off automatically. Think about this. If the input voltage is 120v and 5 amps = 600 watts. The output of a charger is 12v, in theory, the output amps should be 50 amps. That's just theory. Reality, a transformer isn't 100%, so there will be less than 50 amps out.

SOOO, I think a dimmer will work. What is there to loose? The charger is junk. A dimmer is a few bucks. I say by-pass the brain box with a dimmer and then tell me it doesn't work.

The dimmer will not work.

The "brain box" is on the output side of the transformer not the input side.

The dimmer puts out a chopped voltage that will eat a transformer.A look at the output voltage on a scope will prove it.Dimmers are designed to work into resistive loads not transformers.
