CONDITION : BRAND NEW PRODUCT WITH MANUALS AND SOFTWARE DISK INSIDE ITS ORIGINAL BOX

Key Specifications & Features

1. Primary Function:

   • Automatic Voltage Regulation (AVR) – Maintains generator terminal voltage within tight tolerances.

   • Field Current Control – Adjusts excitation to stabilize power output during load changes.

   • Protection Functions – Includes over/under-voltage, overcurrent, field ground detection, and loss-of-sync prevention.

2. Inputs/Outputs:

   • Analog Inputs:

     • Generator VT (Voltage Transformer) and CT (Current Transformer) signals.

     • Field voltage/current feedback.

   • Digital I/O:

     • Breaker status, enable/disable commands, alarm relays.

   • Communication:

     • Modbus RTU (RS-232/485) for SCADA integration (optional protocols may apply).

3. Power Supply:

   • 125/250V DC (typical for excitation systems) or 120V AC (varies by model).

4. Control Modes:

   • AVR Mode (Voltage Control) – Standard operation.

   • FCR Mode (Field Current Regulation) – Manual override for maintenance.

   • VAR/PF Control – Optional for grid-reactive power management.

5. Environmental Ratings:

   • Operating Temp: -30°C to +60°C (-22°F to +140°F).

   • Humidity: 0–95% non-condensing.

   • Enclosure: Typically IP20 (indoor use; may require additional protection for harsh environments).
