AVR R449

Normal AVR supply power: 2 auxiliary windings(X1,X2,and Z,Z2) Shunt supply: 150V-50/60Hz Rated overload current: 10A, 10s. Electronic built-in(overload,short circuit,and loss of sensing) protection: If excitation current raises over 10 Amps for more then 10 seconds, exciation current will drops automatically to about 1A. To resed AVR protection, generator must be stopped(or by cutting supply voltage to the AVR). Voltage sensing: 5VA insulated transformer with nput voltage
