Upgrade Your Trailer Braking: Hydrapro Alpha G-1200 Actuator Overview

When it comes to towing heavy loads, having a reliable and responsive braking system is crucial for safety and control. The Hydrapro Alpha G-1200 Electric Over Hydraulic (EOH) Actuator offers a significant upgrade over traditional surge brake systems, providing faster response times and improved braking performance for your trailer.

Why Choose the Hydrapro Alpha G-1200?
The Hydrapro Alpha G-1200 is designed to enhance the braking capabilities of trailers equipped with hydraulic drum brakes. It delivers a maximum output pressure of 1,200 psi, ensuring that your trailer's brakes engage quickly and effectively. In fact, the actuator can apply full braking pressure in just 0.84 seconds after receiving a signal from your brake controller, offering a much faster response than many competing systems.

Key Features

Rapid Response Time: Achieves full braking pressure in 0.118 seconds for immediate stopping power.
Robust Construction: Features a durable extruded aluminum housing that minimizes heat buildup and protects internal components.
Sealed Fluid Tank: The isolated, sealed reservoir prevents contamination, ensuring long-term reliability.
Versatile Installation: The rotating 90-degree brake line fitting allows for flexible mounting positions on your trailer frame or within an enclosed compartment.
Compatibility: Works seamlessly with factory or aftermarket EOH-compatible brake controllers without the need for additional adapters.
DOT Compliance: Meets Department of Transportation specifications for safety and performance.

Installation Overview

Installing the Hydrapro Alpha G-1200 involves mounting the actuator to your trailer, connecting the hydraulic lines to your drum brakes, and wiring the unit to your brake controller and breakaway system. The actuator's wiring configuration includes:

Black Wire: 12V DC power
Blue Wire: Brake controller signal
Yellow Wire: Breakaway system
White Wire: Ground

It's important to ensure that your trailer is equipped with a DOT-required battery-powered breakaway device and a 7-way trailer connector to send the necessary signals.
