  • Steam Turbines: Governor valve control and speed regulation.

Performance Parameters

  • Positioning Accuracy: High-resolution feedback processing for precise valve control.
  • Response Time: Millisecond-level actuator response for grid stability.

Material Composition

  • PCB: High-reliability, multi-layer board with conformal coating.
  • Components: Precision analog ICs and high-current driver transistors.

Structural Characteristics

  • Form Factor: Standard Mark V board size.
  • Connectors: High-density connectors for actuator and feedback wiring.

Working Principle
Receives position commands from the Mark V regulator, compares them with actual feedback signals, and generates drive signals to move the actuator to the exact commanded position.

Installation Requirements

  • Follow Mark V installation manuals for proper board placement.
  • Ensure all actuator and feedback cables are properly shielded and grounded.

Usage Precautions

  • Never disconnect actuator wiring while the turbine is in operation.
  • Perform calibration procedures after any board replacement.
