IS200PSCDG1ADB – PWM Power Supply / Contractor Driver Board

The IS200PSCDG1ADB is a critical board in the GE EX2100 Excitation Control System, performing dual functions as a PWM (Pulse Width Modulated) power supply and contactor driver. It plays a vital role in delivering and managing DC power within the exciter cabinet, ensuring the control and regulation of field voltage to the generator.

As a PWM power supply, the board converts AC or DC input to a regulated DC output using pulse-width modulation. This method allows for precise voltage control while maintaining high efficiency and minimizing heat loss. The board is capable of supplying power to various components of the exciter system, including control circuits, contactors, and other logic elements.

In its contactor driver role, the IS200PSCDG1ADB controls the operation of one or more contactors that switch high-power electrical circuits. It monitors status conditions and provides feedback to the control system for effective diagnostics and safety assurance.

Its compact, modular design makes it easy to install and replace in the field, reducing system downtime during maintenance. Built with industrial-grade components, the IS200PSCDG1ADB offers long-term reliability even in demanding generator industrial environments.

The board is most commonly found in GE EX2100 systems for gas and steam turbine applications, where it contributes to the robust and stable operation of the generator’s field excitation system.

Constructed for use in GE EX2100 excitation systems, this board is typically found in gas, steam, and hydro turbine applications, where precise voltage regulation and reliable contactor operation are essential. It supports system redundancy, fault tolerance, and provides real-time operational feedback for system health monitoring.
