Stamford MX321 automatic voltage regulator

The Stamford MX321 is a three phase sensed AVR Automatic voltage regulatorand forms part of the excitation system for a brushless generator. Excitation power is derived from a three-phase permanent magnet generator (PMG), to isolate the AVR control circuits fomr the effect os non-linear loads and to reduce radio frequency interference on the genertor terminals. Sustained generator short circuit current is another feature of the PMG system.
