Product description:
The AS480 is a half-wave phase-controlled AVR which forms part of the excitation structure of the brushless generator. Which also incorporates an interface to the optional excitation boost system(EBS) for the use where short-circuit current safeguarding is required.
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 and temperature.In order to ensure the stability of the product, all AVRs go through 24 hours of high temperature aging test before leaving the factory.
