GE DS200FECBG1A FIELD EXCITER CROWBAR

الوصف

The GE DS200FECBG1A is a specialized circuit board known as a Field Exciter Crowbar or Field Exciter Board. It is a key component of the legacy GE Speedtronic Mark V series of industrial control systems, which are primarily used in the power generation industry for controlling gas, steam, and wind turbines.

Key Features and Function

• Field Excitation Control: The board’s main function is to manage the excitation of a synchronous generator. This involves controlling the flow of current to the generator’s field windings, which in turn controls the generator’s output voltage.
• Crowbar Functionality: The term “crowbar” refers to a safety circuit designed to quickly and safely de-excite the generator. If a fault is detected (e.g., an overvoltage condition), the crowbar circuit rapidly discharges the energy stored in the generator’s magnetic field to protect the equipment from damage.
• Mark V Series: This board is an integral part of the Mark V series, a legacy control system known for its high-reliability and triple-redundant architecture. The board plays a crucial role in ensuring the safety and stability of the power generation process.
• On-Board Diagnostics: The board is equipped with various diagnostic features, including jumpers for configuring the board’s behavior and an overvoltage protection controller. These features are essential for troubleshooting and for ensuring the safe operation of the system.
• Obsolete Status: As a component of the discontinued Mark V series, the DS200FECBG1A is an obsolete part. It is no longer manufactured by GE and is typically sourced from new old stock, surplus vendors, or specialized repair and refurbishment companies.
