GE DS200SHVIG1BFC SCR High Voltage Interface Board

Product Details:

The GE DS200SHVIG1BFC is a specialized Silicon Controller Rectifier (SCR) High-Voltage Interface Card designed exclusively for GE’s Mark V Turbine Control System—a legacy platform and one of the final GE product lines to integrate the patented Speedtronic control technology. It serves as a critical interface between the drive’s SCR bridge and key components like the PCCA (Power Connect Card), power supply, and instrumentation card.

Its core functionality revolves around signal conversion and voltage management: it accepts low-range input signals and converts them into differential frequency outputs, which are then transmitted to the drive’s power supply card for processing. It also features 17 configurable Berg-type jumpers that provide additional attenuation for line and bridge voltages. Three on-board LED indicators alert operators to blown fuses, enabling quick fault detection.

Key Features:
SCR Bridge Interface Core Role: Acts as a dedicated interface between the drive’s SCR bridge and critical components (PCCA, power supply, instrumentation card), enabling seamless power and signal transfer for turbine control.

Precise Signal Conversion: Translates low-voltage input signals into differential frequency outputs, ensuring compatible signal transmission to the power supply card for accurate processing.

Configurable Voltage Attenuation: 17 Berg-type jumpers allow customized attenuation of line and bridge voltages, adapting to diverse drive operating conditions.

Real-Time Fault Alerts: Three LED indicators provide immediate visual feedback on blown fuses, simplifying troubleshooting and reducing downtime for maintenance.

Fragile, Voltage-Sensitive Design: Minimal voltage-limiting hardware makes it highly sensitive to voltage fluctuations and physically delicate, requiring strict adherence to GE’s installation guidelines to prevent damage.
