ABB UNITROL 1020 is a digital automatic voltage regulator (AVR) and excitation controller designed to regulate the terminal voltage of synchronous generators. It controls the generator's excitation current to maintain stable output voltage as the electrical load changes.
It is used in generator sets, industrial power plants, and other power-generation applications where reliable voltage regulation and generator excitation control are required.
