Brand: GE (General Electric)
Model: DS200FSAAG1ABA
Full name: Field Supply Amplifier Board, a power supply and gate amplifier board specifically for GE Mark V turbine / gas turbine control systems, classified as a dedicated industrial control board for these systems. It is often referred to as a system power driver module.
Compatible systems: GE Mark V turbine unit control systems (gas turbines, steam turbines)
Core Functions
System stable voltage power supply + power amplification: Provides a large power 24VDC stable voltage power supply for the SCR controllable silicon drive circuit of the main control system and the on-site actuators, and performs power amplification on the control gate signals to drive valves and speed actuators.
Loop power distribution and overcurrent / overvoltage protection: Built-in two 30A fuses for power distribution to the turbine protection loop and emergency shutdown loop, providing rapid fuse melting protection for the main control hardware in case of abnormalities.
Signal isolation: Isolates weak electrical control signals from the high-power drive circuits, suppresses on-site electromagnetic interference, and ensures the stability of the unit control.
Fault self-diagnosis: Board-mounted multiple test points and status indicator lights, enabling rapid troubleshooting of power short circuits, overloads, and under-voltage faults.
