Features:
- Acquires the exciter PPT three-phase supply through transformer-based voltage measurement.
- Defines the G1 EBAC range for converter inputs from 651 to 1400 V ac.
- Feeds synchronized bridge-voltage information toward three controller paths through EAUX.
IS200EBACG1A gives the regulator a phase reference taken directly from the converter input.
Its three transformer circuits preserve the individual ac phases before the feedback leaves the board.
The G1 designation distinguishes this high-voltage range from the lower-voltage G2 configuration.
The General Electric IS200EBACG1A Bridge AC Feedback Board is supported by Apter Power with quotation and technical assistance.

Three-Phase Acquisition
- Signal Source: IS200EBACG1A receives the exciter PPT ac supply.
- Sensing Method: Three transformer circuits measure the three input phases.
- Measured Quantity: The board develops bridge ac voltage feedback.
- Functional Boundary: EBAC handles supply-voltage sensing rather than gate-drive output.
Line Reference
- Control Purpose: IS200EBACG1A supplies the phase reference used for SCR firing.
- Reference Point: Timing follows the incoming ac line measured at the PPT supply.
- Control Relationship: Voltage acquisition and firing synchronization remain linked through the EBAC feedback.
- System Context: The function belongs to the EX2100e power-conversion path.
Controller Fanout
- Intermediate Board: IS200EBACG1A passes its outputs through EAUX.
- Primary Path: One feedback route reaches the M1 controller.
- Redundant Path: A second route serves the M2 controller.
- Common Path: The remaining output is delivered to the C controller.
G1 Selection Boundary
- Group Identity: IS200EBACG1A is the G1 hardware configuration.
- Assigned Range: G1 covers 651 to 1400 V ac converter inputs.
- Lower Range: Inputs up to 650 V ac are assigned to the separate G2 configuration.
- Selection Point: The converter input voltage determines the required EBAC group.
