Whats the difference between time delayed and proportional breaking systems?

A time delay controller like the part # 80550 is so named because there is a delay between the time that you initially apply the brakes in your tow vehicle and the time that the controller reaches maximum preset power output. Unlike a proportional brake controller, which activates your trailer's brakes based on the deceleration of your tow vehicle, a time-delayed controller sends power out in the same way, with the same gradual delay, no matter the braking situation. Although this delay always exists, it can be adjusted by changing the sync setting. The sync controls how quickly the braking power is ramped up.

A proportional brake controller like the P2 part # 90885 senses when and how your tow vehicle brakes with an internal inertia-based sensor. This sensor responds to the deceleration of your tow vehicle as you brake by signaling the controller to send out enough power to your trailer brakes so that they are activated with an intensity that matches. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.
