Product Description

AS480 Automatic Voltage Regulator:

Product Description

The AS480 is a half-wave phase-controlled AVR which forms part of the excitation structure of the brushless generator. Which also incorporatesan interface to the optional excitation boost system(EBS) for the use where short-circuit current safeguarding is required.

Positive voltage build 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 auxiliarywinding 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%, In response to his sample voltage, the AVR controls the power fed to the exciter field, and hence the main field, to sustain the machine output voltage within the specified limits, compensating for load, speed, temperature and power factor of the generator.
