AVR SX460 For Stamford Alternators
SX460 Automatic Voltage Regulator
SX460 AVR is a half -wave phase-controlled thyristor type Automatic Voltage Regulator (AVR) and forms part of the excitation system for a brush-less generator.In addition to regulating the generator voltage,the AVR circuitry includes under-speed and sensing loss protection features.Excitation power is derived directtly from the generator terminals.Positive voltage build up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the AVR.,The AVR is linked with th main stator windings and the exciter field windings to provide closed loop control of the output voltage with load regulation of +/-1.0%.In addition to being powered from the main stator,the AVR also derives a sample voltage from the output windings for voltage,the AVR control the power fed to the exciter field,and hence the main field , to maintaion the machine output voltage within the specified limits,compensating for load,speed temperature and power factor of the generator.
A frequency measuring circuit continually monitors the generator output and provides output under-speed protection of the excitation system ,by reducing the outputvoltage proportionally with speed below a pre-settable threshold.A manual adjustment is provided for factory setting of the under frequency roll off point.(UFRO).This can easily be changed to 50 or 60Hz in the field by push on link selection.Porvision is made for the connection of a remote voltage trimmer ,allowing the user fine control of the generator’s output.
