Mark V Power Connect Card Assembly | GE DS200PCCAG9ACB

Product Description

The DS200PCCAG9ACB is a high-performance Power Connect Card Assembly (PCCA) engineered for the General Electric Speedtronic Mark V control system. As a foundational power distribution module, this board is responsible for regulating and routing incoming supply voltages—typically 125 VDC or AC—into the stable DC rails required by the system's logic processors, communication modules, and I/O terminal boards. It serves as the "power heartbeat" of the Mark V rack, ensuring deterministic operation of the turbine control electronics.

This specific revision, DS200PCCAG9ACB, features advanced power conditioning circuitry designed to provide ripple-free outputs across multiple voltage levels, including +5 VDC and ±15 VDC. To safeguard the entire control core, the board includes integrated hardware protection against over-voltage, over-current, and thermal anomalies. Its industrial-grade PCB design utilizes passive convection cooling, making it suitable for the continuous, high-temperature environments characteristic of gas and steam turbine enclosures.

Application & System Strategy

The DS200PCCAG9ACB is typically installed in the power distribution section of the Mark V panel. It acts as the primary interface between the external power supply and the internal logic bus. In TMR (Triple Modular Redundancy) configurations, a failure in the PCCA board can lead to a loss of the associated control core (<R>, <S>, or <T>), making it a critical spare part for plant availability. The "9ACB" revision level indicates specific component optimizations for enhanced power stability over earlier PCCAG5A or G8A models.

Frequently Asked Questions

Is the DS200PCCAG9ACB backward compatible with G5A or G9A models?Yes, the DS200PCCAG9ACB is generally backward compatible with standard PCCA boards in the Mark V series. However, the "9ACB" designation often includes improved filtering capacitors and thermal resilience. Always verify your specific system's voltage rail requirements before hot-swapping power components.

Can this board be used in Mark VI systems?No. The DS200PCCAG9ACB is architecturally specific to the Mark V Speedtronic backplane. Mark VI systems utilize the IS200 series power modules, which feature different physical connectors and voltage regulation protocols.
