The AVR has the faclity for droop CT connection,to allow parallel running with other similarly equipped generators.SX440 is a two phase sensed Automatic Voltage Regulator(AVR) and forms part of the exciation system for a brush-less generator.The AVR senses the voltage in the main generator winding and control the power fed to the exciter stator and hance the main rotor to maintain the generator output voltage within the specified limits, compensating for load sprrd,temperature and power factor of the generator.Vibration:20 -100HZ (50mm/sec), 100Hz -2kHzColour: BlackMaterial: metal + PCSensing Input:Voltage: 190-264V ac max, 1 phase 2 wireFrequency: 50-60HZ nominalPower inpotVoltage: 140-220 V ac max, 3 phase,3 wireCurrent: 3A/phaseFrequency: 100-120HZ nominalOut putVoltage: max 120V/DCCurrent: continuous 2.7A/DCIntermittent 6A for 10 secsResistance: 15 ohms minimumRegulation: +/-1%Thermal drift: 0.03% per deg.C change in AVR ambientSoft start pamp time: 3 secTypical system responseAVR respone: 10msFiled current to 90%: 80msMachine Volts to 97%: 300msExternal voltage adjustment: +/-10% with 1k ohm 1W trimmerUnder frequency protectionSet point: 95%HZSlope: 170% down to 30HZUnit power dissipation: 12 watts maximumAnalogue inputMaximum input: +/-5V/DCSensitivity 1V for 5% Generator Volts(adjustable)Input resistance 1k ohmQuadrature droop input10 ohms burdenMax.sensitivity:0.07A for 5% droop OPFMax.input:0.33AOver excitation protectionSet point:75V/DCTime relay:10 secEnvironmentalVibration:20 -100HZ (50mm/sec), 100Hz -2kHzOperating temperature: -40ºC to +70 ºCRelative Humidity: 95%Storage temperature: -55ºCto +80ºCPackage Contents: 1 x Automatic Voltage RegulatorOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
