The AN-5W-203B Automatic Voltage Regulator (AVR) is a highly reliable electronic control module engineered for precise voltage regulation in industrial generator sets. Housed in a robust rectangular aluminum enclosure and fully potted in a black protective compound, this AVR is built to withstand harsh operating environments, heavy vibrations, and moisture. The advanced circuit board features dual transformers and a high-capacity electrolytic capacitor to ensure stable power delivery. Designed for user-friendly installation and tuning, it includes multiple white screw terminal blocks for secure wiring and a series of blue trimmer potentiometers for accurate voltage and stability adjustments. It is an essential component for maintaining consistent and safe power output in demanding industrial applications.
