FUNCTIONAL DESCRIPTION:

IS200EPDMG1A is an Exciter Power Distribution Module manufactured and designed by General Electric as part of the EX2100 Series used in GE Excitation Turbine Control Systems. The IS200EPDM Exciter Power Distribution Module (EPDM) is used in the EX2100 Excitation Control to provide power for the control, I/O, and protection boards of the exciter. It is mounted on the side of the IS200EPBP Exciter Power Backplane (EPBP) receives 125 V dc power from the station battery and accepts one or two 120 V ac power inputs for backup. All power supply inputs are received through a board-mounted terminal block (TB1) and are filtered. Each ac supply is rectified to 125 V dc in an external Ac to Dc Converter (DACA). The resulting two or three dc voltages are diode coupled through external diodes to create the dc source power supply, designated P125V and R125V. These voltages are center grounded and are nominally +62.5 V and 62.5 V to ground. The module is chassis-grounded and safety-grounded through four of the board mounting holes.

Two 12-plug connectors (JDACA1 and JDACA2) connect the AC power sources from the terminal block (AC1 and AC2) to the external DACA#1 and DACA#2, and return the DACA outputs to the 125 V dc lines (P125 and R125). Individual power supply outputs to each of the exciter boards are fused, have an on/off toggle switch (except the EXTB board), and a green LED indicator to show power availability. The outputs supply up to three IS200EGPA Exciter Gate Pulse Amplifier Boards (EGPA), the IS200EXTB Exciter Terminal Board (EXTB), and three IS200EPSM Exciter Power Supply Modules (EPSM) serving three controllers. A separate connector is provided for each output and these are wired to the EPBP for distribution.

FEATURES:

• Power Distribution: The module efficiently distributes power to various components within the turbine control system, ensuring reliable operation.

• Voltage Regulation: It regulates the voltage supplied to critical components, maintaining stable electrical parameters to prevent fluctuations that could damage sensitive equipment.

• Fault Detection: The module is equipped with sensors and diagnostic capabilities to detect faults or abnormalities in the power distribution system, enabling timely intervention and maintenance.

• Overload Protection: It includes mechanisms to protect against overloads or short circuits, safeguarding both the module itself and connected devices from damage.

• Remote Monitoring: Many Exciter Power Distribution Modules offer remote monitoring capabilities, allowing operators to monitor power distribution status and performance from a centralized control room.

• Modularity: The module is often designed with modular components, facilitating easy installation, maintenance, and scalability as per the requirements of the turbine control system.
