Three Phase Automatic Voltage Stabilizer AVR R448 For Brushless Diesel Generator

Diesel Generator Automatic Voltage Stabilizer AVR R448 Easy Spare Parts For Brushless Generator

Description

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 excitation, a permanent magnet generator (PMG) added to the alternator supplies the AVR with a voltage that 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.
