Product Description

Overview

The GE DS200DCFBG1BLC is a precision DC Power Supply Feedback Board designed for GE’s Mark V Speedtronic Control System. It delivers regulated DC power and signal conditioning to SCR bridges, ensuring reliable operation of gas and steam turbines. Built for industrial durability, this board manages multiple voltage rails and feedback signals, serving as a key interface between control logic and power conversion hardware.

Compact and rugged, the board supports high-current gate drive pulses, provides clean control power, and protects downstream electronics with integrated fusing and isolation barriers. It is widely used in turbine excitation, variable speed drives, and legacy Mark V installations requiring high reliability.
