D350 Automatic Voltage Regulator

The Leroy Somer D350 Automatic Voltage Regulator (AVR) is a state-of-the-art digital control system engineered to maintain precise voltage output in generator applications requiring rated field current up to 5 amperes. Designed by Leroy Somer, a global leader in alternator technology, the D350 AVR provides superior voltage regulation performance for industrial, commercial, and backup power generation systems. This advanced digital regulator automatically adjusts the excitation current supplied to the alternator’s rotor winding, ensuring stable, consistent voltage output regardless of load variations or engine speed fluctuations. The D350 represents the next generation of voltage regulation technology, offering enhanced accuracy, reliability, and diagnostic capabilities that far exceed traditional analog AVR systems.
