Automatic Voltage Regulator AVR-20 for Datakom Generator Alternator 4066R D155W-1 S/N 12128-UPApplication: For Datakom Generator Alternator Notice: Introduction: AVR 20 Voltage Regulator is an electronic device that allows the alternator to produce fixed output voltage. It has open chassis, molded resin design and is intended to be mounted on the alternator terminal box. AVR 20 measures the voltage between one of the alternator phases and the neutral point and adjusts the DC voltage applied to the excitation winding until the desired voltage
