The STAMFORD MX341-2 is a two-phase sensed Automatic Voltage Regulator (AVR) that forms part of the excitation system for a brushless generator. It provides closed-loop control by regulating the main field current to maintain the generator’s output voltage within specified limits. The MX341-2 is powered by a Permanent Magnet Generator (PMG) which ensures a constant and isolated power source, making it resilient to non-linear loads and improving motor starting performance. Key features include under-frequency roll-off (UFRO) protection, soft-start voltage ramping, and over-excitation shutdown, ensuring reliable and safe generator operation.
