The 200 series regulators are shunt regulators, that is they tap off field current from the alternator, which control the voltage or the cosíåÛåÎÖ of the alternator by adjus- ting the field current in the exciter field coil. They can operate alone or with a short circuit corrector, also called a parallel booster in the event that a short circuit current is necessary or when large auxiliaries need to be started. They are completely encapsulated and are suitable for fitting inside or outside the machine.SAME EXACT AVR AS:SDMO Voltage Regulator 330410022 AVRSpecificationsSensing input : < 2VA isolated by internal transformerPower input : 630VA 100V single-phase or 63V three- phase 50/60 Hz maximumTI input parallel operation : 1Amp, 1VAPower output : 63V 7Amp continuous with 90V 10Amp peaksExciter resistance : 9 Ohms minimumRegulation precision : íåäåα 1% of Un and íåäåα 0.02 of cosíåÛåÎÖ at rated powerTemperature shift : 1% of Un for delta T ambient of - 20íåäåÎÁ to 25íåäåÎÁC or 25íåäåÎÁ to 70íåäåÎÁCResponse time : < 10 ms - Operating temperature : -20íåäåÎÁC to +70íåäåÎÁCStorage temperature : -40íåäåÎÁC to +85íåäåÎÁCSizeheight 115 mmwidth 115 mmdepth 230 mmweight 1 kg (2 Lbs)
