Selection Recommendations
Choose IS200EXHSG4AEC for the most demanding grid stability applications requiring ultra-fast response, predictive algorithms, or highest processing performance. Select over “3” series boards when maximum performance is required. Verify “AEC” firmware matches your excitation system and grid code requirements. Deploy redundant boards for critical high-speed control paths. Confirm rack power supply can provide the higher current (3.0A) required by the “4” series board.
Precautions and Important Notes
Use ESD-safe handling. Verify communication wiring and settings. The IS200EXHSG4AEC draws 3.0A (+5V) – verify rack power supply capacity before installation. Confirm “AEC” firmware supports your specific excitation system and grid code requirements. Never interrupt firmware updates. Document all configurations. Store spares in anti-static packaging. Do not mix IS200EXHSG4AEC with “3” or “1” series boards in redundant pairs without verifying identical firmware. Allow 30 seconds boot time. Test all ultra-fast control and advanced functions thoroughly during commissioning. The IS200EXHSG4AEC is critical for fast excitation response and grid stability – ensure all control parameters, field forcing limits, and grid code settings are verified before placing in service. If replacing a “3” series board with the IS200EXHSG4AEC, verify power supply capacity and equipment compatibility before installation. The higher performance of the “4” series may require firmware updates to other system components or adjustment of control parameters to fully utilize enhanced capabilities. Consider power supply upgrades if multiple “4” series boards are installed in the same rack.
