Features:
- Live Maintenance with Individual Load Isolation
- Enhanced Diagnostic Visibility via Fused Outputs
- Robust Power Mixing via Diode Coupling
The General Electric IS200EPDMG1BAA-IS200EPDMG1B includes dedicated toggle switches (SM1C, SM2, SM3A, SM4A) for each output channel. This allows plant engineers to selectively depower a faulty EGPA board or an EPSM power supply while leaving the rest of the Mark VI system online, eliminating unnecessary turbine trips during diagnostic procedures.
Visual inspection is simplified with status LEDs and clearly labeled fuses (FUT13-16). The General Electric IS200EPDMG1BAA-IS200EPDMG1B enables rapid fault identification—if an LED is off, engineers check the corresponding fuse without needing a multimeter. This feature directly supports GE’s "Maintainability First" design philosophy for the EX2100 series.
Unlike standard terminal blocks that short supplies together, the General Electric IS200EPDMG1BAA-IS200EPDMG1B uses internal diode coupling to combine 125Vdc battery and rectified 115Vac sources. This prevents back-feeding current from one source to another, ensuring stable P125V/N125V power rails even if one input source fails or sags during generator startup.
The IS200EPDMG1BAA-IS200EPDMG1B General Electric Exciter Power Distribution Modulee may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
