Voltage Regulator AS440

Applicationt: 

Unversal

Production Description:

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

Positive voltage build up from residual levels is ensured by
the use of efficient semiconductors in the power circuitry of
the AVR. The control and voltage sensing circuits have
separate terminals, allowing the excitation power to be
resulting directly from the stator winding for necessary
applications or from an auxiliary winding if sustained short
circuit performance is essential.

The AVR is linked with the main stator windings and the
exciter field windings to present closed loop control of the
output voltage with load regulation of +/- 1.0%.
