Energy Storage	1000 µF at 200V

GE 246B2357BA DS200EXDEG1ABA stores energy using two large electrolytic capacitors. Together, they provide 1000 µF at 200V rating for field current hold-up. This energy storage maintains excitation during 40 millisecond power interruptions. Therefore, the board keeps generator voltage stable through brief sags.

Design and Integration

This board uses six-layer PCB construction with high-voltage isolation barriers for safety. Consequently, the GE 246B2357BA DS200EXDEG1ABA operates reliably from -15°C to +55°C ambient temperature.

For installation, you need M4 screws for the four mounting holes. The board draws 200 mA typical current from the 125V DC supply. The 4006L4114AAG001 marking indicates Mark V system compatibility. We recommend using 14 AWG wire for the DC input connection.

Practical Application

This Mark V exciter board regulates generator field current for turbine systems. It receives firing commands from the main controller via backplane. The GE 246B2357BA DS200EXDEG1ABA also provides voltage and current feedback for closed-loop control. Therefore, it forms the excitation control stage for GE Mark V turbine systems.
