🔹 Product Description

The GE DS2020EXPSG3 is an EXPS Exciter Power Supply Module designed for the GE Speedtronic Mark V turbine control system and associated EX2000 brushless generator excitation applications. It is a DS2020 Special Assembly, Group 3 configuration, consisting of multiple PCB assemblies mounted within a metal carrier structure. The assembly includes the DS200EXPS power-supply board and a DS200GDPA board, with transformers, heat sinks, fuses, capacitors, resistors, terminal connections, and diagnostic LEDs. The module provides power-conditioning and monitoring functions for the excitation system and includes current-limiting functionality when energized from the station battery.
