Governing Systems Overview
GAC’s Speed Control Units are precise speed controls designed and manufactured in various configurations to meet application requirements using the latest analogue 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 conformably coated to be vibration and moisture resistant.
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 electromechanical 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.
GAC’s synchroniser provides automatic, trouble free and safe phase and frequency matching of two sets in 3 - 4 seconds or less. Built in in-phase monitor provides breaker closure signal. In case of failure, manual synchronising is still possible by a speed trim potentiometer input on most speed control units.
GAC’s load sharing units measures continuously the generator sets power and provides precise, proportional load sharing between any number of sets, independent of engine/fuel system variations.
GAC’s accessories and extension modules allow users to custom design solutions to meet individual project requirements, increasing the communication and remote monitoring functionality of the controllers.
Speed Sensors are available in more than two dozen configurations that are combinations of thread size, length, and connector style. All are designed and tested to operate within a temperature range of -55°C to 105°C.
