General Electric IS200EPBPG1A Exciter Power Backplane Board

The GE IS200EPBPG1A is an industrial-grade Exciter Power Backplane Board engineered to function within the Mark VI and Mark VIe excitation control systems developed by General Electric (GE). This backplane board serves as the central electrical and mechanical connection interface for exciter power components. It provides stable mounting and efficient power distribution to multiple plug-in modules used in the excitation system, particularly in synchronous generator applications.

The IS200EPBPG1A is a critical element in the power section of the exciter control cabinet. It acts as a bus system that facilitates communication and power sharing between boards such as power converters, control processors, and I/O interfaces. This modular backplane design enhances flexibility, allowing for the swift replacement or addition of exciter control components without the need to rewire the entire system.

Built with high-reliability connectors and rugged materials, this board is designed to endure harsh environmental conditions, such as those found in power generation facilities, including thermal cycling, high humidity, and electrical noise. Its high current-carrying capacity and efficient heat dissipation further ensure long-term performance and system integrity.
