Overview

The DS200SDCIG1AFB is a critical component of GE’s Mark V Series, a system widely used for gas and steam turbine control and management. As part of one of the last GE series developed under the Speedtronic™ platform, this board represents the culmination of decades of innovation dating back to the Mark I in the late 1960s.

This module functions as a DC power supply and instrumentation interface for DC2000 drive systems, enabling precise control and monitoring through its integrated circuitry and configurable components.
