Description:
1.SX440 is a two-phase sensed automatic voltage regulator (AVR) and forms part of the excitation system
for a brushless generator.
2. The AVR senses the voltage in the main generator winding and controls the current supplied to the magnetizing stator and
Raise the main rotor to keep the generator output voltage within the specified limits, compensating for load shedding, temperature and power factor of the generator.
3. Excitation power is obtained from a three-phase permanent magnet generator (PMG), to isolate the AVR control circuits from the effects of non-linear loads and to reduce radio frequency interference at the generator terminals. The PMG system.
4.The AVR unit has the option of switching CT connection, to allow parallel operation with other similarly equipped generators.
