Performance Parameters
- Response Time: Millisecond-level response to grid disturbances and setpoint changes.
- Accuracy: High-precision voltage and current measurement capabilities.
Material Composition
Industrial-grade PCB with conformal coating to protect against moisture, dust, and corrosive gases in power plant environments.
Structural Characteristics
Compact board design with multiple multi-pin connectors for interfacing with power bridges, sensors, and redundant controllers.
Working Principle
Receives voltage and current feedback signals, compares them against reference setpoints, and calculates the required firing angles for the thyristor bridge to regulate excitation current.
Installation Requirements
- Ensure all signal and power connectors are fully seated and locked.
- Verify jumper settings match the specific generator and exciter configuration.
Usage Precautions
- Handle with extreme care to avoid damaging sensitive analog components.
- Ensure proper grounding of the excitation system to prevent ground loops.
