GENERATOR AVR R448 with top quality Leroy Somer R448

Specifications

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 taps at:

Terminals 0-110V=95 to 140V

Terminals 0-220V=170 to 260V

Terminals 0-380V=340 to 520V
