Product Overview
OverviewTheR120 Leroy Somer Automatic Voltage Regulator (AVR)is a precision-engineered OEM component designed to maintain stable voltage output in generator systems powered by Leroy Somer alternators. Manufactured exclusively in France by Leroy Somer, this genuine AVR ensures your generator delivers consistent, reliable power by automatically adjusting the excitation current to the alternator's rotor. Whether you're operating critical backup power systems, industrial generators, or mobile power units, the R120 AVR provides the voltage stability essential for protecting sensitive equipment and ensuring uninterrupted operation. This compact, robust voltage regulator is built to withstand demanding environmental conditions while delivering precise voltage control across varying load conditions.As anoriginal equipment manufacturer (OEM) part, the R120 AVR is engineered to exact specifications for seamless integration with compatible Leroy Somer alternator models. Unlike aftermarket alternatives, this genuine Leroy Somer voltage regulator guarantees optimal performance, longevity, and compatibility with your generator system. The R120 features advanced circuitry that responds instantly to load changes, maintaining voltage stability within tight tolerances to prevent equipment damage and ensure safe, efficient power generation. When your generator's voltage regulation fails, replacing the AVR with a genuine R120 unit restores factory performance and protects your investment in quality power generation equipment.Key SpecificationsSpecificationValueModel NumberR120ManufacturerLeroy Somer (France)Voltage Regulation Range±2.5% steady stateInput Voltage85-264 VAC (single phase)Frequency Range50/60 HzRegulation Accuracy±0.5% to ±2.5%Response TimeLess than 100msOperating Temperature-40°C to +70°CDimensions (L x W x H)140mm x 95mm x 55mm (approximate)WeightApproximately 0.4 kgProtection RatingIP20MountingDirect mount to alternatorCompatible Alternator ModelsTheLeroy Somer R120 AV
