Description
The GE FANUC DS200NATOG1ABB and DS200GDPAG1ALF are GE Speedtronic Mark V turbine control system components designed for industrial turbine automation applications. The DS200NATO board is used as a signal interface and termination board, while the DS200GDPA board is a high-frequency power supply board that provides regulated power conversion for Mark V control and excitation-related assemblies.
The DS200GDPAG1ALF is a revised version of the GE Mark V High Frequency Power Supply Board. It supports AC and DC input operation and provides high-frequency power conversion for turbine control equipment, including gas turbine, steam turbine, and industrial drive systems.
This module combination is commonly found in legacy GE Speedtronic Mark V control platforms where reliable replacement boards are required for maintenance, refurbishment, and system life extension projects.
