Generator controllers provide comprehensive generator protection and control for single or multiple gen-sets based on field proven technologies. The primary function of Generator controler is to manage and protect the generator in preference to the engine, which is not a direct concern. GC can be used in applications where engine management or protection is not required or in cases where the generator is powered by another source such as a turbine controlled by an external PLC. The controller is suitable for use in LandBased and Marine applications.
