AVR AS440 Automatic Voltage Regulators , 1 Phase Brushless Generator Parts
SpecifiCAT-parts-partsions
Comptible brushless generator parts- Stamford AVR AS440( OEM part and Genuine part)
Pictures show as below
Stamford AVR AS440 is a half wave phase controlled thyristor type AVR and forms part of the excitation system for a brush-less generator. The design employs Surface Mount Technology (SMT) for high integration of features in a small footprint AVR.
