Product Description Product Features 1.Introduction:SX460 is a half-wave phase- controlled thyristor type Automatic Voltage Regulator and forms part of the excitation system for a brushless generator. In addition to regulating the generator voltage, the AVR circuitry includes under speed and sensing loss protection to ensure safe, reliable control of the generator. Positive voltage build up from residual levels is ensured by the use of proficient semiconductors inthe power circuitry of the AVR. Which is linked with the main stator windings and the exciter field windings to offer closed loop control of the output voltage with load regulations of +/- 1.5% Stability adjustmentUnder frequency roll off adjustment 2.Technical data:Parameter sheet of Standford AVR SX460InputVoltageJumper selectable 95-132V ac or 190-264V acFrequency50-60 Hz nominalPhase1OutputVoltagemax 90V dc at 207V ac inputCurrentcontinuous 4A dc, intermittent 6A for 10 secsResistance15 ohms minimumRegulation+/- 1.0%Thermal Drift0.05% per deg.
