GE DS200PCCAG6A
- Product Name: GE Mark V / DC2000 Power Connect Card (PCCA)
- Product Introduction: The DS200PCCAG6A functions as a power connect / coupling board for GE Mark V Speedtronic turbine control systems and DC2000/AC2000 drives. It isolates and scales armature voltage/current feedback for SCR bridges, bridging low-voltage control logic and the high-power drive section.
