GENERATOR AVR SX460 VOLTAGE REGULATORWarranty: 1 YearGross Weight: 0.4kgsStock Status: In stockPart No. : SX460Replaced Brand: StamfordFunction: Stamford AVR SX460Usage: SX460 Stamford AVRCompatible with: Stamford SX460 AVRGeneral descriptionSX460 VOLTAGE REGULATOR is a half-wave phase-controlled thyristor type Automatic Voltage Regulator (VOLTAGE REGULATOR) and forms part of the excitation system for a brush-less generator.In addition to regulating the generator voltage, the VOLTAGE REGULATOR circuitry includes under-speed and sensing loss protection features. Excitation power is derived directly from the generator terminals.Positive voltage build up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the VOLTAGE REGULATOR.The Stamford Generator VOLTAGE REGULATOR SX460 is linked with the main stator windings and the exciter field windings to provide closed loop control of the output voltage with load regulation of +/- 1.0%.In addition to being powered from the main stator, the VOLTAGE REGULATOR also derives a sample voltage from the output windings for voltage control purposes. In response to this sample voltage, the VOLTAGE REGULATOR controls the power fed to the exciter field, and hence the main field, to maintain the machine output voltage within the specified limits, compensating for load, speed, temperature and power factor of the generator.A frequency measuring circuit continually monitors the generator output and provides output under-speed protection of the excitation system, by reducing the output voltage proportionally with speed below a pre-settable threshold. A manual adjustment is provided for factory setting of the under frequency roll off point, (UFRO). This can easily be changed to 50 or 60 Hz in the field by pushon link selection.Provision is made for the connection of a remote voltage trimmer, allowing the user fine control of the generator's output.
