FUNCTIONAL DESCRIPTION:

IS200PSCDG1ABB is a Power Supply and Contactor Driver Board manufactured and designed by General Electric as part of the EX2000 Series used in GE Excitation Control Systems. The Power Supply and Contactor Driver board (PSCD) is powered from the dc link through stab-on terminals DCPL1 (+) and DCPL2 (-). The control operates from 80 - 400 V dc as nominal range inputs. Transient operation to 600 V dc is possible during maximum operation of the dynamic discharge. This board produces control power for distribution to the other control module boards. The main supply produces ±24 V, ±15 V, and +5 V for control boards (LDCC and TCCB) A 17.7 V ac squarewave is distributed through high-frequency transformers to the gate driver and LTB inputs power supplies. Auxiliary to the main supply is supplies for generating isolated 70 V dc (sufficient to power 13 LUP inputs ) and an isolated SHVI/SHVM power for future applications. The contactor control power supply from the PSCD board is sized to deliver up to 0.75 A dc. Power is taken directly from the dc link and converted to 105 V dc by a buck converter. The MDA contactor is enabled through an optically coupled signal, which is logically in parallel with the coil of K1. Relay K1 is driven from the LDCC board when the control is commanded to run. Relay K86 is used as the control permissive to run an emergency stop. Dropping out K86 will immediately stop the regulator. The coil voltage is from the 70 V dc power supply on the PSCD board.

FEATURES:

• High Power Handling Capability: Able to handle high power requirements typical in turbine applications, ensuring stable and continuous operation

• Voltage Regulation and Stability: Provides precise voltage regulation to ensure consistent power delivery to critical components of the turbine system, maintaining stability and performance.

• Current Monitoring and Limiting: Monitors current flow and limits it within safe thresholds to prevent overload conditions that could damage the turbine or associated equipment.

• Contactor Control and Relay Outputs: Interfaces with contractors to control the activation and deactivation of various components within the turbine system. Offers relay outputs for switching high-power loads such as motors, valves, and actuators.

• Optoisolation and Noise Immunity: Incorporates optoisolation to ensure electrical isolation between control circuits and power circuits, minimizing noise interference and enhancing system reliability.

• Compatibility with Turbine Control Signals: Supports various input signals and communication protocols commonly used in turbine control systems, allowing seamless integration and compatibility with existing control infrastructure.
