The MX341 Stamford AVR (Automatic Voltage Regulator) ensures accurate and stable voltage control for synchronous generators in demanding environments. Because modern power systems require dependable regulation, this AVR continuously monitors generator output and instantly adjusts excitation levels. As a result, it maintains steady voltage even during sudden load fluctuations.

Moreover, the MX341 supports both shunt and AREP excitation systems, which allows flexible integration with various Stamford alternators. In addition, its soft-start voltage ramp feature gradually builds generator output; therefore, it protects connected equipment from electrical stress during startup. Not only does this improve operational safety, but it also extends alternator lifespan.

Furthermore, the unit delivers ±1% voltage regulation accuracy under normal operating conditions. Consequently, businesses benefit from improved power quality and reduced risk of sensitive equipment malfunction. Even under varying frequency conditions, the adjustable under-frequency roll-off (UFRO) function maintains controlled performance.

Advanced Features for Reliable and Efficient Operation

Beyond precision regulation, the MX341 includes practical adjustment controls that simplify commissioning. For example, users can fine-tune voltage stability, over-excitation limits, and UFRO settings directly on the unit. As a result, operators gain greater control over generator behavior in different applications.

Additionally, built-in EMI suppression reduces electrical noise interference; thus, the AVR performs reliably in industrial and commercial installations. Because of its compact design and clearly marked terminals, installation remains straightforward and efficient. Whether used in new generator assemblies or as a replacement regulator, integration remains smooth and hassle-free.

Ultimately, the MX341 Stamford AVR delivers dependable voltage control, operational flexibility, and long-term durability. Therefore, it stands as a trusted solution for generator professionals who demand consistent and high-performance power regulation.
