1 Phase AC Electric Generator Automatic Voltage Regulator AVR Stamford SX440
1 Phase AC Electric Generator Automatic Voltage Regulator Stamford AVR SX440
AVR
Description
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.
