Product Overview

• Part No: 3BHE039203R0101, equivalent model GVC736CE101
• Brand: ABB

• Category: Thyristor Trigger Control BoardThis control board is a critical power electronic component in high-power conversion systems. It receives optical fiber command signals from main controllers and generates precise driving pulses to control thyristor modules. It realizes accurate phase angle regulation, rectification and power adjustment. Meanwhile, it continuously collects operating status of power devices and feeds fault signals back to the main control unit to guarantee secure and stable operation of the whole power system under heavy-load working conditions.
