GE Fanuc DS200PCCAG5ACB Power Connect Card

The GE DS200PCCAG5ACB is a high-horsepower Power Connect Card (PCCA) for the Speedtronic Mark V system. It features 12 gate pulse connectors, pulse transformer logic for SCR bridge control, and four configurable voltage jumpers. Designed for high-reliability drive systems, this G5-group board eliminates onboard snubbers to optimize power density in demanding industrial turbine applications.

Technical Functionality

The GE Fanuc DS200PCCAG5ACB operates as a critical Power Connect Card (PCCA) within the Speedtronic Mark V turbine control system. This module serves as the primary hardware interface between the SCR power bridge and the drive’s control circuitry. By utilizing integrated pulse transformers, the DS200PCCAG5ACB effectively feeds gate drive signals to the SCR bridge, allowing for precise control of power switching. Furthermore, this board is specifically classified for high-horsepower applications, as it streamlines its architecture by offloading snubbers and attenuation strings to other locations within the system.

Operational Performance

This power connect card facilitates high-speed signal distribution through 12 plug connectors designed to transmit both forward and reverse gate pulse signals. Because the module must communicate with the system’s power infrastructure, it includes a dedicated connector for interfacing with DCFB-type power supply boards. Additionally, the DS200PCCAG5ACB executes localized voltage regulation and protection by incorporating leg reactors and fuses. Technicians can also configure the system voltage by utilizing four onboard wire jumpers (WP4, WP3, JP2, and JP1), ensuring the board adapts to specific site requirements.
