A high performance speed control system results when a GAC actuator is installed on an engine and electronically connected to compatible GAC governing system components. The design baseline for GAC actuators incorporates fast responses, multi-voltage usage and proven reliability to allow for more precise control.
GAC employs its field proven electromechnical design which provides proportional actuator movement based on actuator coil current.
All of GAC actuators are easy to install with no maintenance required. GAC also offers a complete line of speed control devices for use with our actuators;
all of which are 100% field-proven tested.
GAC’s Speed Control Units are precise speed controls designed and manufactured in various configurations to meet application requirements using the latest analog and digital control technologies. Reverse battery polarity and fail-safe protection in the event of loss of speed sensor signal or battery voltage is incorporated in every GAC Speed Control Unit. A wide variety of application needs can be satisfied with GAC’s constant or variable speed governing in isochronous or droop operation. All circuit boards are hard potted or conformally coated to be vibration and moisture resistant.
The Magnetic Speed Sensor detects when ring gear teeth, or other ferrous projections, pass the tip of the sensor. Electrical impulses are produced by the sensor’s internal coil and sent to the speed control unit. The signal from the magnetic speed sensor, teeth per second (Hz.), is directly proportional to engine speed. Speed sensors are available in various lengths in both U.S. and metric threads. Wire leads, military connectors, packard connectors, automotive connectors or stud terminals are also available. Over 35 styles currently available.
GAC’s low-cost JDR series of J1939 data readers allow users to monitor trouble codes and standard engine parameters. More advanced models support Tier IV engines with diesel particulate filters (DPF). Harsh applications are no match for JDR’s rugged design. With installation and setup a breeze, users will be monitoring engine vital signs and configuring parameters in no-time.
The GAC provides a complete line of analog modules for generator sets. Module functions include load sharing, synchronizing, voltage regulation, speed ramping, voltage matching and a large assortment of analog modules to interface with other brands of controls such as Woodward, Cummins, CAT, etc.
In answer to market demands, GAC offers an advanced gaseous fueled engine management system with exhaust emissions control technologies to meet the tough standards sanctioned in the United States and the rest of the World.
GAC’s total system approach results in a cost effective solution that offers the greatest potential for improvements in both engine efficiency and exhaust emissions while providing many features.
Basic Fuel and Ignition Management System (FIMS) for low pressure applications using a venturi mixer and stepper motor control valve. The user interface software is completely designed by GAC. System includes a built-in engine speed governor. Extremely cost effective and capable. System includes two separate modules which can operate stand-alone depending on the application needs.
