SX460 Automatic Voltage Regulator (AVR) | Stamford Generator Set Spare Parts

The SX460 has become obsolete and has been replaced by the AS440. For detailed information, kindly get in touch with your local authorized STAMFORD | AvK Parts and Service dealer. Previously employed with our UC22 and UC27 alternators, the SX460 was an analog, 2-phase sensing, self-excited automatic voltage regulator (AVR). It operated by connecting the AVR with the main stator windings and the exciter field windings to achieve closed-loop control of the output voltage. To ensure authenticity, purchase the replacement AVR, AS440, exclusively from an authorized STAMFORD.
