Product Description
50HZ/60HZ Automatic Voltage Regulator AVR R448 The R448 AVR is powered by two auxiliary windings which are self-sufficient of the voltage match circuit, the first winding has a voltage in proportion to that of the alternator(characteristic shunt), the second has a voltage in proportion to the stator current(compound characteristic: booster effect). The power supply voltage is rectified and filtered before being used by the AVR monitoring transisitor.
