Stamford AVR SX440 for generator

详情

SX**0 is a half wave phase restricted thyristor type AVRand forms part of the excitation system for a brushlessgenerator.



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 bythe use of efficient semiconductors in the power circuitry of the AVR.

The control and voltage sensing circuits haveseparate terminals, allowing the excitation power to beresulting directly from the stator winding for necessaryapplications or from an auxiliary winding if sustained shortcircuit performance is essential.



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