MX322 GENUINE STAMFORD AVR (MX321 REPLACEMENT)

The MX322™ analogue, 3-phase sense Automatic Voltage Regulator (AVR) forms part of the excitation system for a brush-less alternator. Excitation power is derived from a 3-phase permanent magnet generator (PMG) to isolate the MX322™ AVR control circuits from the effects of non-linear loads and to reduce radio frequency interference on the alternator terminals.
