The Stamford MX341 is a two-phase sensed AVR that creates part of the excitation system for a brushless generator. It enables closed loop control by anticipating the alternator output voltage at the main stator windings before modifying the exciter stator field strength.
It will sense the voltage in the main generator winding and will control the power fed to the exciter stator, allowing the rotor to sustain the generator output voltage within the identified limits. This compensates for speed, temperature, load and the power factor of the generator.
