The GE IS200EPSMG1AED Exciter Power Supply Module serves as the critical power hub for GE’s
EX2100 excitation control system, primarily functioning to convert unregulated AC input power
(120V/240V AC ±10%, 50/60Hz, with auto-switching to adapt to global grids) into stable, isolated DC
power—delivering two dedicated output channels (24V DC ±0.5% at 10A max for powering I/O
modules like IS200EMIOH1A and ground detectors such as IS200EGDMH1A, and 15V DC ±0.5% at 5A
max for sensitive feedback boards including IS200EDCFG1ADC). It integrates robust protection
mechanisms, including 3kV AC input-output isolation to block EMI/RFI interference from high-voltage
generator components, resettable overcurrent fuses (0.5–10A) to prevent damage from short circuits,
and auto-recovery over-temperature shutdown (triggered at 85°C) to avoid burnout during high-load
operation. Additionally, the module supports N+1 redundancy with <10ms auto-failover via the EISB
(Exciter Internal Serial Bus), enabling seamless power transition to a backup unit in mission-critical
setups to eliminate excitation system downtime. It also facilitates real-time diagnostics by
transmitting output voltage, current, and internal temperature data to the EX2100’s DSPX controller,
supporting predictive maintenance via HMI tools like GE CIMPLICITY. Built with IPC-CC-830B Class 3
conformal coating, it operates reliably in harsh industrial environments (-40°C to 70°C, 5%–95% non-
condensing humidity), ensuring consistent performance in power plants, offshore wind farms, and
steel mills while maintaining full compatibility with the EX2100 ecosystem for plug-and-play
integration.
