Product Overview

The GE IS200EBRGH2A is an Exciter Bridge Interface Board (EBRG) designed for the EX2100e Series in GE Excitation Control Systems.
It interfaces the EX2100e control system with SCR bridges and associated I/O components, providing precise bridge control and feedback.

Functional Description

• Bridge Interface: Connects to the SCR bridge, fan controls, thermistor sensors, and current sensors.
• Control Architecture: Supports simplex and redundant configurations via one or two UCSB controllers using HSLA.
• Power Management: Accepts 125 V DC from station battery and 115/220 V AC from external supplies; AC converts to stable DC bus via DACA modules.
• Mounting & Compatibility: Fits in the Power Conversion Cabinet; compatible with 77 mm or smaller thyristors (H2) and 100 mm thyristors (H1).

Key Features

1. Interface and Control

• Enables precise feedback and control of the SCR bridge.
• Ensures seamless communication for efficient power management.

2. Mounting Location

• Mounted in Power Conversion Cabinet alongside PCM, DC circuit contactors, and circuit breakers.

3. Controller Compatibility

• Independently manages bridge firing and control; not interfaced with Controller C.

4. Power Supply and Integration

• Operates at 125 V DC via EDIS.
• Interfaces with 42 mm, 52 mm, and 77 mm thyristor systems.

5. System Integration

• Supports simplex, warm backup, and parallel bridge converters.
• Ensures smooth coordination between control systems and power bridges.
