We provide the following brands of replacement generator AVRs for you to choose from, with additional new products being added each year:
A Stamford AVR refers to an Automatic Voltage Regulator specifically designed for use with generators manufactured by or compatible with Stamford alternators. Stamford, a brand owned by Cummins Generator Technologies (now part of Cummins Inc.), is renowned for producing high-quality alternators used in generator sets. The models we have as belows:
Models: SX460,SX440,AS440,MX341,MX321,AS540,AS480,MX450.
The Leroy Somer AVR Series refers to Automatic Voltage Regulators (AVRs) designed for use with alternators and generator sets manufactured by Leroy Somer, a renowned brand known for its high-quality rotating machines including alternators, motors, and related control systems. Leroy Somer is now part of Nidec Corporation.
Model: R120, R150, R220, R230, R250, R438, R448, R449, R450, R450M, R450T.
A General Brushless AVR refers to an Automatic Voltage Regulator designed for use with brushless generators. These AVRs play a critical role in maintaining a stable output voltage from the generator, regardless of changes in load or operating conditions. The term "brushless" indicates that the generator does not use brushes for electrical connections between the rotor and stator, which reduces wear and tear, increases reliability, and minimizes maintenance requirements.
Model:GAVR-8A GAVR-12A GAVR-15A GAVR-20A GAVR-35A GAVR-50A GAVR-75A GAVR-100A
A Mecc Alte AVR refers to the Automatic Voltage Regulator used in alternators produced by Mecc Alte, a leading company in the production of alternators and generator sets. Mecc Alte alternators are known for their high quality, reliability, and performance across a wide range of applications including industrial, commercial, and residential backup power solutions.
