AS440 is a half wave phase controlled thyristor type AVR and forms part of the excitation system for a brushless generator. The design employs Surface Mount Technology (SMT) for high integration of features in a small footprint AVR.

The AS440 is an analogue, 2-phase sensing, self-excited automatic voltage regulator (AVR). The AS440 incorporates Surface Mount Technology (SMT) to its design. The AS440 is supplied as standard to the STAMFORD ® S4 and STAMFORD ® HC5 alternators and is an option for the STAMFORD ® UC22 and UC27 alternators.

The AVR provides closed loop control by sensing the alternator output voltage at the main stator windings and adjusting the exciter stator field strength. Voltage induced in the exciter rotor, rectified by the rotating diodes, magnetises the rotating main field which induces voltage in the main stator windings.
