1. Product Description
The IS200EACFG2B acts as a bridge between the SCR bridge and the control panel, measuring three-phase AC supply voltage (up to 1000Vrms) and current feedback to enable real-time adjustment of excitation systems. Key features include:
- Dual Feedback Measurement: Simultaneously monitors AC supply voltage (via potential transformers) and current feedback (via air-core current transformers), providing accurate data for excitation control.
- Fiber-Optic Isolation: Uses high-speed fiber-optic links (plastic or hard-clad silica) to transmit signals to the EBKP backplane board, ensuring voltage isolation and immunity to electromagnetic interference.
- Flexible Voltage Scaling: Supports single three-phase input voltage up to 1000Vrms (G2 version), with ±20% tolerance for varying grid conditions.
- Modular Design: Mounts directly in the exciter auxiliary cabinet, with three RS232 ports (J504, J509, J514) for connection to EBKP modules and up to 90 meters of cabling.
