GE IS200EPSMG2AEC Product Description
Product Overview
The GE IS200EPSMG2AEC is a high-reliability exciter power supply module designed for GE’s Speedtronic Mark VI/VIe distributed control systems and EX2100 excitation regulator systems in gas and steam turbine applications. As a critical component in turbine excitation control, it converts input voltage into stable DC outputs to power the EX2100 regulator and associated control modules, ensuring precise voltage regulation and fault protection for generator systems.
Engineered for rugged industrial environments, the module features a 32-bit digital signal processor (DSP) for advanced power management and diagnostics. Its compact design supports DIN rail or wall mounting, making it adaptable to various control cabinet layouts. Built-in LED indicators provide real-time status monitoring for power, fault, and communication activity, simplifying maintenance and troubleshooting.

Main Features and Advantages
Dual Input Voltage SupportThe module accepts 125V DC directly from the power distribution module (PDM) or 380–480V AC via an optional converter, providing flexibility in power source selection. This dual compatibility ensures seamless integration into both legacy and modern turbine control systems.
Precision Power ConversionEquipped with a buck regulator and push-pull inverter, the module converts input voltage to stable DC outputs (+5V, ±15V, +24V) for the EX2100 regulator. The transformer-based design offers high-voltage isolation (2500Vrms) to protect against voltage spikes and ground loops.
Redundancy and Fault ProtectionIn redundant systems, two IS200EPSMG2AEC modules are deployed (one in the primary backplane and one in the redundant backplane), ensuring uninterrupted power during maintenance or component failure. Built-in overcurrent and short-circuit protection safeguards connected modules from damage.
Compact and Modular DesignThe 1U rack-mount form factor minimizes space requirements in control cabinets, while the modular layout simplifies replacement. The module’s lightweight construction (0.3kg) and conformal coating enable reliable operation in harsh environments with high vibration and humidity.
Advanced DiagnosticsReal-time LED indicators and fault logging via the Mark VI HMI allow quick identification of issues such as input voltage irregularities or communication failures. For example, a European combined-cycle plant used these diagnostics to resolve a persistent ground fault alarm within 15 minutes, avoiding a $50,000 production loss.
Application Field
The IS200EPSMG2AEC is widely used in power generation, oil & gas, and petrochemical industries where stable excitation control is critical:
Power Plants: Powers EX2100 regulators in gas/steam turbines to maintain grid stability. A 750MW coal-fired plant in India reported a 40% reduction in maintenance costs after adopting this module.
Offshore Platforms: Protects turbine-driven compressors from electrical faults caused by saltwater corrosion. A Gulf of Mexico platform used the module to detect a developing ground fault, avoiding a $200,000 shutdown.
Petrochemical Facilities: Supports precise control of reactor pressure and flow in turbine-driven pumps. A German plant achieved a 30% reduction in power distribution maintenance thanks to its diagnostic capabilities.

Installation and Maintenance
Pre-Installation Preparation:
Verify compatibility with Mark VI/VIe systems (software version 6.5+ for Mark VI, 7.0+ for Mark VIe) and EX2100 firmware.
Use ESD-safe tools (anti-static wristband, insulated screwdrivers) to protect the module’s DSP components.
Label cables to match terminal markings (e.g., “TB1-COMMON,” “TB2-ALARM”) to avoid wiring errors.
Maintenance Recommendations:
Perform monthly visual inspections for loose connectors, corrosion, or illuminated fault LEDs.
Use compressed air (30 PSI max) to clean dust from the module and DIN rail.
Quarterly, test redundant input failover via the Mark VI HMI and measure output voltage (24V ±5%) with a multimeter.
Replace the module with a factory-calibrated unit if faults persist, ensuring compliance with GE’s excitation system protocols.
