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.

Digital Governors
GAC digital governors are solid state microprocessor based speed control units that offer precise (+/- 0.25%) speed control with fast response to transient load changes in isochronous and droop modes.
