ABB KUC720AE01 Output Module Technical Specifications

The ABB KUC720AE01 output module is an important functional unit in the UNITOL static excitation system, mainly used to convert the adjustment signal of the excitation controller into power output, thereby directly driving the excitation current to supply the generator rotor. It is usually used in conjunction with the KUC711AE101 excitation controller to form a complete automatic voltage regulation (AVR) and excitation system.

This module belongs to high reliability power electronic units, integrating power output circuits, protection circuits, and status monitoring. It is a key component for achieving generator voltage stability and reactive power support.
