Description
The GE IS200AEPGG1AAA is a high-reliability exciter power supply module designed for GE’s Mark VIe turbine control systems. It delivers regulated DC power to generator field windings, ensuring stable excitation voltage/current for synchronous machines. The module features integrated diagnostics, redundancy support, and rugged construction for critical power generation applications.
Features
- Dual-Channel Input: Accepts 120/240V AC or 125V DC inputs with automatic source switching.
- High-Current Output: Supplies 125V DC at 25A continuous (30A peak) to excitation systems.
- Auto-Feedback Control: Internal voltage/current regulation (±0.25% accuracy).
- Redundant Operation: Parallel-capable for N+1 configurations (active load sharing).
- Robust Design: Operates at -30°C to +65°C (-22°F to +149°F) with 95% non-condensing humidity (IEC 60068-2).
- Protections: Over-voltage, over-current, short-circuit, and overtemperature safeguards.
- Front-Panel Indicators: LED status for power, faults, and load activity.
