The GE DS200GDPAG1AEB is a high-frequency power supply board for Mark V Turbine Control Systems. Rated for up to 700W, it supports 80–132 VAC or 105–140 VDC inputs. Featuring a 27 kHz inverter and 120 VDC output, this board provides isolated, regulated control power for critical industrial drive and excitation applications.
The GE DS200GDPAG1AEB functions as a high-frequency power supply (HFPS) module within the Mark V Speedtronic Turbine Control System. Specifically designed to provide regulated control power, this board accommodates both AC and DC input sources to ensure maximum flexibility across diverse industrial power grids. The unit typically delivers between 600 and 700 Watts of power, supporting critical control logic, gate drivers, and excitation hardware within GE drive assemblies. By utilizing high-frequency switching technology, the DS200GDPAG1AEB maintains a compact footprint while offering superior efficiency and signal stability.
The board integrates a complex array of power processing stages to convert raw input into stable control voltages. Key functional blocks include:
To facilitate rapid troubleshooting and status verification, the DS200GDPAG1AEB features several onboard visual indicators. Technicians can monitor the board’s health through:
As a “GDPAG1AEB” model, this board represents an evolved version within the GDPA family, incorporating “AEB” level revisions for enhanced thermal management and component longevity. The board mounts securely within the Mark V cabinet, but technicians must prioritize clear airflow paths due to the heat generated by the 700W power conversion process. Proper grounding is essential to ensure the 27 kHz inverter does not introduce electromagnetic interference (EMI) into the high-speed data ribbon cables.
