Basic Information

Model: GFD233A

Product Code: 3BHE022294R0101

Manufacturer: ABB

Function and Feature

Excitation Control: It is mainly used to control the excitation system of generators. It ensures that the appropriate current passes through the excitation coil, thereby affecting the electromagnetic field of the generator and controlling the generator's output. This helps maintain the stability and reliability of the generator's output voltage and power.

Communication Capability: The module is equipped with a communication interface, which enables it to exchange data with other control systems or monitoring equipment. This facilitates its integration into the entire power system, allowing for remote monitoring and control, and improving the intelligence and automation level of the power system.

Generator Protection: It includes protection functions for generators. Under adverse conditions, such as over - voltage, over - current, or low - frequency faults, it can automatically take appropriate measures to protect the safe operation of the generator, reducing the risk of generator damage and improving the reliability of the power generation system.

High Precision and Stability: The GFD233A has high - precision control capabilities, which can accurately control the excitation current of the generator to meet the requirements of different working conditions. It also has good stability and can work properly in harsh environments, ensuring the stable operation of the excitation system.

Modular Design: It adopts a modular design, which facilitates expansion and customization according to specific user requirements. Users can add or replace modules as needed to meet different application scenarios. This design also simplifies maintenance and upgrades, reducing maintenance costs and downtime.

Technical Specifications

Input Voltage: Usually supports a wide range of input voltages to adapt to different power supply systems, such as 85 - 264 V AC or 100 - 300 V DC.
