MX321 AUTOMATIC VOLTAGE REGULATOR
The MX321 is a three phase sensed Automatic Voltage Regulator and forms part of the excitation system for a brush-less generator. Excitation
power is derived from a three-phase permanent magnet generator (PMG), to isolate the AVR control circuits from the effects of nonlinear loads
and to reduce radio frequency interference on the generator terminals. Sustained generator short circuit current is another feature of the PMG
system.

MX341 AUTOMATIC VOLTAGE REGULATOR
The MX341 is a two phase sensed Automatic Voltage Regulator and forms part of the excitation system for a brush-less generator. Excitation power
is derived from a three-phase permanent magnet generator (PMG), to isolate the AVR control circuits from the effects of nonlinear loads and
to reduce radio frequency interference on the generator terminals. Sustained generator short circuit current is another feature of the PMG
system.

AS440 AUTOMATIC VOLTAGE REGULATOR
The SX440 is a half-wave phase-controlled thyristor type Automatic Voltage Regulator (AVR) and forms part of the excitation system for a
brush-less generator. In addition to regulating the generator voltage, the AVR circuitry includes under-speed and sensing loss protection
features. Excitation power is derived directly from the generator terminals.
