Product Description

Products Description
AVR R448
The circuitry of the R448 Automatic Voltage Regulator (AVR) provides closed loop control of the alternator output voltage by
regulating the exciter field current. The primary winding has a voltage in ratio to that of the alternator (characteristic shunt),
the next has a voltage in proportion to the stator current (compound characteristic: booster effect). Which is powered by two
auxiliary windings which are independent of the voltage equal circuit. The power supply voltage is rectified and filtered before
being used by the AVR monitoring transistor. With PMG excitatioin, a permanent magnet generator (PMG) added to the alternator
supplies the AVR with voltage which is free of the main alternator winding. This is built-in at the rear of the machine and
connected to the R448 AVR, and the ST9 jumper must be disconnected.
