Are you asking does it always go to full power, or can you make it go to full power?
It has a slider on the bottom that allows you to manually activate the trailer brakes. The farther the slide is moved from right to left the more power is sent to the brake magnets. If the max voltage you have set on the dial is 6 volts (the maximum voltage sent to the brake magnets when depressing the brake pedal) you can manually move the slide all the way to 12 volts to add "Boost" when hauling a heavy load. It doesn't automatically go to full power. The power applied is a function of how far you manually move the lever.
I normally use ours pulling a dual axle trailer behind a Ford truck. When the trailer is empty it weighs about 2,100 lbs. I set the max voltage to 3 - 4 volts. It's enough to slow the trailer without locking the brakes. When hauling an 8,000 lb load I can either raise the voltage to 8 volts or manually apply more voltage by manually sliding the lever. Generally I just raise the voltage using the dial. It's easier than trying to remember to add boost everytime you step on the brakes.
Here's a link to the Tekonsha site.
If you scroll down to the Prodigy2 picture you can see a small bump on the bottom right of the controller. That's the manual slider I'm referring to
