ELECTRONIC PROPORTIONAL BRAKE CONTROLLER

The Power Sentry Proportional Trailer Brake Controller uses an internal inertia sensor to match trailer braking directly to your tow vehicle's deceleration in real time, for smooth, natural stops with less sway and less wear on both vehicle and trailer. An adjustable gain dial lets you fine-tune power for your trailer's weight, a manual override lever gives you independent trailer braking on grades or while backing up, and an in-cab digital display shows output level and flags connection issues at a glance. Precise, level under-dash mounting ensures accurate readings, and it's compatible with 1 to 4 axle electric and electric-over-hydraulic trailer brake systems — ideal for boat, utility, horse, and RV trailers alike.
