Product Description
Stamford M40FA640A/A Automatic Voltage Regulator (AVR)
The Stamford M40FA640A/A (Mark I) Automatic Voltage Regulator (AVR) is a premium, industrial-grade component engineered to deliver precise and stable voltage control for synchronous generator sets. Designed for rigorous industrial applications, this AVR features an integrated heavy-duty heat sink and a toroidal inductor to ensure optimal thermal management and electrical reliability under load. It provides operators with comprehensive tuning capabilities through built-in adjustment potentiometers for Voltage (VOLT), Frequency (FREQ), Amps (AMP), Stability (STAB), and Slope (SLOPE). The unit is equipped with clearly marked terminal connections for excitation outputs, multi-point sensing inputs (S1-S6), and standard power supply lines (N, U), making it an essential upgrade or replacement for maintaining safe and consistent generator performance.
