1 general information r 450m. Is reduced as indicated in the next diagram see 3214 fast acting fuses. R450 controls the excitation current in order to maintain the output voltage of the alternator. With arep excitation the r 448 electronic avr is powered by two auxiliary windings which are independent of the voltage match circuit. It incorporates the latest technology and efficient components to achieve a high degree of miniaturisation when applied to a 3 phase and 1 phase ac brushless generator within its input and output limits. It is designed for alternators with a shunt arep or pmg excitation.
