Automatic Regulator AVR SX440 For Generator parts

Description

SX440 is a half-wave phase-controlled thyristor type Automatic Regulator and forms part of the excitation system for a brushless generator. In addition to regulating the generator , the AVR circuitry includes under speed and sensing loss protection to ensure safe, reliable control of the generator

The Propose employs sur mount technology (SMT) for high integration of features in a minute footprint AVR. Positive build up from residual levels is ensured by the use of proficient semiconductors in the power circuitry of the AVR. The control and 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. Which is linked with the main stator windings and the exciter field windings to offer closed loop control of the output with load regulations of +/- 1%
