MX321 is a three phase sensed Automatic Voltage Regulator and forms part of the excitation system for a brushless generator.
Excitation power is derived from a three phased permanent magnet generator(PMG),to isolate the AVR control circuits from the effects of nonlinear loads and to reguce radio frequency interence on the generator terminals.
Sustained generator short circuit current is another feature of the PMG system.
Adjustable soft start circuitry is included to provide a smooth controlled build up of generator output voltage.
