SX440 Automatic Voltage Regulator Power Electronic Voltage Regulator Switch Diesel Generator Spare Parts(Ordinary)

AdjustersSX440 AUTOMATIC VOLTAGE REGULATOR (Automatic Voltage Regulator)SX440 is a half.wave phase-controlled thyristor type Automatic Voltage Regulator (Automatic Voltage Regulator) and forms part of the excitation system for a brush-less generator.In addition to regulating the generator and voltage, the Automatic Voltage Regulator circuity includes features under-speed and sensing loss protection features. Excitation power is derived directly from the generator terminals.Automatic Voltage Regulator SX440SENSING INPUTVoltage190-264V acFrequency50-61 Hz nominalphase1 Wire2 OUTPUTVoltagemax 90V at 207V ac inputCurrentcontinuous 4A , intermittent 6A for 10 secsResistance15 ohms minimumREGULATION+/- 1.0%THERMAL DRIFT0.04% per deg.
