Model IS200EBACG1A is an Exciter Bridge AC Feedback Board, and is part of the Excitation Control, EX2100e series. Within the series, this model is designed to be a digital controller of the Thyristor-based Systems of 42, 53, 77, and 100 millimeters. When being connected to the system the model connects to a high-speed serial link (HSSL) communication device as well as an Exciter Auxiliary Interface (EAUX) board.
When in the EX2100e system the IS200EBACG1A model will act as an inverting thyristor (SCR), full-wave, three-phase power conversion module (PCM). The EX2100e system is equipped with advanced technology, which is the ‘e’ indicator at the end of EX2100. When this model is connected it requires forced air-cooling, when the units are operating in a redundant application, the cooling modules will be energized during operation.
The IS200EBACG1A model within the EX2100e system can be used to control software and will support high-performances. There is a transducer system and a software transducer system that can be operated with the EBAC unit. Some of the outputs of the software transducer system are generator frequency, generator active current, and generator voltage.
While the IS200EBACG1A model may not be as readily available on the market due to it no longer being produced by General Electric. The model does not have a corresponding part-specific manual but the information needed can be found in the GEA-S1302A EX2100e manual, there is also a brief fact sheet labeled as GEA-S1244 that gives more information about the EX2100e series.
