MIFIIPI55E10HI00 GE xciter Primary Driver Module (EPDM)
1. Product Description
The IS200EPDMG1A (P/N: MIFIIPI55E10HI00) is an Exciter Primary Driver Module (EPDM) used in GE’s Speedtronic™ Mark VI turbine control systems. It interfaces between the turbine controller and the generator excitation system, converting control signals to high-power DC output for the exciter field. Supports both brushless and static excitation systems.
2. Product Series
- Series: GE Mark VI Excitation Control I/O
- Family: Part of the EPDM/P (Exciter Primary Driver Module) family.
- Compatibility: Works with Mark VI controllers (e.g., IS215UCVx) and exciter cabinets (EX2000/EX2100).
3. Key Features
- High-Current Output: Dual-channel 130V DC / 10A continuous (20A peak).
- Redundant Channels: Independent A/B channels for fail-safe operation.
- Fiber-Optic Isolation: Galvanic isolation between control logic and power stages.
- Real-Time Diagnostics: Monitors output current, voltage, and temperature.
- Hot-Swap Support: Replaceable without turbine shutdown.
4. Functions & Roles
- Exciter Field Control: Drives generator field current for voltage regulation.
- Protection: Implements over-current, under-voltage, and overtemperature trips.
- Signal Conversion: Translates low-voltage control signals (0–10V) to high-power DC output.
- Redundancy Management: Auto-switches to backup channel on fault detection.
5. Applications
- Power Generation: Gas/steam turbine generator excitation control.
- Hydroelectric Plants: Automatic Voltage Regulation (AVR) systems.
- Industrial Generators: Backup power synchronization & grid compliance.
- Marine Propulsion: Shipboard turbine-generator excitation.
