This manual provides detailed information on the function, principle, usage and maintenance of the EA15A self-excited automatic voltage regulator. It also provides circuit diagrams and installation instructions.
This document is the Operation Manual for the KUTAI EA15A, a self-excited automatic voltage regulator rated for 15 Amps. It is designed for use with general generators and features selectable sensing input voltage (190-500 VAC) and frequency (50/60 Hz). The manual provides specifications, wiring diagrams, and adjustment procedures for voltage, stability, and frequency roll-off.
