Description: Product Description Brushless Generator Voltage Stabilizer AVR SX440-A Model: AVR SX440-A Capacitor: Red Origin: China Product description: Generator avr SX440A SX440-A is a half-wave phase-controlled thyristor type Automatic Voltage Regulator (AVR) and forms part of the excitation system for a brush-less generator. General description: Positive voltage build up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the AVR. The AVR 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 AVR also derives a sample voltage from the output windings for voltage control purposes. In response to this sample voltage, the AVR 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. An analogue input is provided allowing connection to a Newage Power Factor controller or other external devices with compatible output. The AVR has the facility for droop CT connection, to allow parallel running with other similarly equipped generators. ·I am a 10-year gold-medal repair technician and can provide you with professional assistance.
