3 Phase 30KVA Generator Automatic Voltage Regulator AVR AS440
The AS440 ( + Kit replaces SX440 ) is a half-wave phase-controlled
Thyristor type Automatic Voltage Regulator and forms part of the
excitation system for a brushless generator. In addition to
regulating the generator voltage, the AVR circuitry includes
under-speed and sensing loss protection to ensure safe, reliable
control of the generator. The Propose employs surface mount
technology (SMT) for high integration of features in a minute
Positive voltage builds up from residual levels is ensured by the
use of proficient semiconductors in the power circuitry of the AVR.
The control and voltage sensing circuits have separate terminals,
allowing the excitation power to be resulting directly from the
stator winding for necessary applications or from an auxiliary
winding if sustained short circuit performance is essential. Which
is linked with the main stator windings and the exciter field
windings to offer closed-loop control of the output voltage with
load regulations of +/- 1.0%
The AVR voltage sensing terminals continuously sample the output
windings for voltage control purposes. In response to this sample
voltage, the AVR controls the power fed to the exciter field, and
hence the main field, to maintain the machine output voltage within
the specified limits, compensating for load, speed, temperature and
power factor, of the generator.
