As480 Avr For Stamford Generator

Stamford AS480 AVR Original Replacement Automatic Voltage Regulator is built to fully replace the original version, same fit, form and function.

AS480 AVR for Stamford Generator is a half wave phase controlled AVR which forms part of the excitation structure of the brushless generator. The plan employs Surface Mount Technology (SMT), custom moldings and heat sinks to create a compactAVR assembly. The AVR also incorporates an interface to the optional Excitation Boost System (EBS) for the use where short-circuit current safeguarding is required.
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 +/- 1.0%. Inresponse to his sample voltage, the AVR controls thepower 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.
