De-Excitation Module GE DS200EXDEG1ADA | Mark V Turbine Series

GE DS200EXDEG1ADA De-Excitation Control Board – Product Description

Product Overview

The GE DS200EXDEG1ADA is a dedicated de-excitation control board engineered for Mark V turbine control systems used in modern power generation environments. It manages the rapid removal of field energy during generator trip events and ensures stable shutdown performance. Moreover, the board maintains reliable interaction with high-energy field circuits, allowing operators to protect critical assets without interrupting turbine sequencing. Each unit is manufactured in the USA and tested to meet the demanding requirements of industrial generator protection.
