What is the output of the transformer inside? is it 12vrms?

Hello.The output voltage of this power adapter is 12V,Output DC tip size is 5.5mm x 2.5mm, compatible with 5.5mm x 2.1mm. Thanks.

Is this power supply compatible with a seperate dimmer switch?

No, most definitely not. It is a switching power supply, and may fail if you connect it to a phase control lamp dimmer/speed control.

What awg gauge is the internal wire that is connected to the 5.5x2.5mm dc plug? thanks!

Big enough to handle the 10 amp load which it does, no problem.
