Description / Overview
The ABB PFEA112-65 is an advanced excitation controller module for ABB’s UNITROL 6000 system, providing precise automatic voltage regulation (AVR) and generator control. It ensures stable synchronous generator operation, optimized dynamic response, and grid compliance.
In parallel, the PFEA112-20 tension electronics module monitors dual load cell inputs, offering voltage and current outputs with adjustable filtering. Real-time measurements of A, B, A+B, and A-B values are displayed clearly, while Profibus-DP integration allows seamless communication with distributed control systems.
These modules combine microprocessor-based intelligence and reliable design, delivering high performance in industrial environments, including hydropower, thermal power, and other generator applications. Moreover, both modules are suitable for replacing legacy parts, ensuring backward compatibility.
