D350 Leroy Somer AVR – Automatic Voltage Regulator

OverviewTheLeroy 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.What sets the D350 apart from conventional voltage regulators is its programmable digital architecture and comprehensive monitoring capabilities. The unit can be fully configured usingLeroy Somer EasyReg Advanced software, allowing technicians to customize parameters to match specific application requirements and optimize generator performance. The D350 features an integrated event logger function that records operational data and fault conditions, making troubleshooting and preventive maintenance significantly easier and more effective. Additionally, the optionalNFLink® wireless communication moduleenables remote parameter configuration and data retrieval without the need for physical connection to the unit, streamlining commissioning and service procedures. Fully compliant withIEC 60034 international standards, the D350 delivers the reliability and performance demanded by mission-critical power generation applications worldwide.Key SpecificationsSpecificationValueModel NumberD350Rated Field Current OutputUp to 5 Amperes DCRegulation TypeDigital Automatic Voltage RegulationInput Sensing Voltage170-265V AC (configurable)Regulation Accuracy±0.5% to ±
