Leroy Somer AVR R448

Specification

Normal AVR supply power: 2 auxiliary windings

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 than 10 seconds, excitation current will drops automatically to about 1A.

To reset AVR protection, generator must be stopped(or by cutting supply voltage to the AVR).

Protection of power inputs by fuses F1

Voltage sensing 5VA insulated transformer with input voltages taps at:

Terminals 0-110V=95-140V

Terminals 0-220V=170-260V

Terminals 0-380V=340-520V
