GE Mark V DS200TCPDG1BEC Power Distribution Board TCPD
The GE DS200TCPDG1BEC (Part Number: DS200TCPDG1BEC) is a critical DC Power Distribution Board (TCPD) designed for the Mark V Speedtronic Turbine Control System. As a primary power regulation hub, the DS200TCPDG1BEC converts 125 VDC nominal input into specialized, regulated voltages required by the SDCC and other high-performance control boards. This module is essential for maintaining the operational integrity of GE Frame 5, 6, 7, and 9 gas and steam turbines, ensuring that control logic remains powered by clean, surge-protected energy.
The "BEC" revision level of the DS200TCPDG1BEC features an enhanced protective coating and optimized circuitry for harsh industrial environments. It provides multiple configurable output channels and incorporates hardware-level protection via replaceable fuses. To facilitate maintenance and rapid fault finding, the board is equipped with localized LED indicators and accessible test points, allowing engineers to verify DC rail health without disconnecting the system from the turbine backplane.
