GE DS200PCCAG6A EX2000, Power Connect Card

  • SCR Bridge Interface: The DS200PCCAG6A serves as the gateway between the digital control cards and the high-current SCR bridge. It uses pulse transformers to safely amplify and isolate the low-power control signals, providing the gate drive signals necessary to turn on the SCRs. This precise control is essential for regulating the flow of current to the generator’s field.
  • Power and Signal Routing: Beyond just gate pulses, the card handles the routing of critical feedback signals, such as armature voltage, from the power section back to the control logic. It also provides a central connection point for power lines within the cabinet.
  • Protection Circuits: The board is equipped with snubber circuits for low-to-medium horsepower applications. These passive networks protect the power switches from damaging voltage spikes and oscillations that occur during switching, enhancing the reliability and lifespan of the SCRs.
  • Revision G6A: This specific hardware revision is notable for its compatibility with J, K, and M frame drive assemblies. Unlike some other versions of the card, the G6A is a fixed configuration and typically lacks user-configurable jumpers, simplifying installation in specific applications.
