SX460 is a half-wave phase-restricted thyristor type

Automatic Voltage Regulator (AVR) and forms part of the
excitation structure for a brush-less generator.
In accumulation to regulating the generator voltage, the AVR
circuitry includes under-speed and sensing loss security
features. Excitation power is derived directly from the
generator terminals.

Positive voltage build up from residual levels is ensured by
the use of proficient semiconductors in the power circuitry of
the AVR.

The AVR is linked with the main stator windings and the
exciter field windings to offer closed loop control of the
output voltage with load regulation of +/- 1.5%.
