    Description:

    Positive Voltage Build Up From Residual Levels Is Ensured By The Use Of Efficient Semiconductors In The Power Circuitry Of The Avr. The Power And Voltage Sensing Circuits Have Separate Terminals, Allowing The Excitation Power To Be Derived Directly From The Stator Winding For Basic Applications Or From An Auxiliary Winding If Sustained Short Circuit Performance Is Required.
    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.
    Over Excitation Conditions Are Limited To A Safe Period By A Protection Circuit Within The Avr.
    Provision Is Made For The Connection Of A Remote Voltage Trimmer, Allowing The User Fine Control Of The Generator's Output.
