Specification
Normal Automatic Voltage Regulator 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 Automatic Voltage Regulator protection, generator must be stopped(or by cutting supply voltage to the Automatic Voltage Regulator).
Protection of power inputs by fuses F1
Voltage sensing 5VA insulated with input voltages taps at:
Terminals 0-110V=95-140V
Terminals 0-220V=170-260V
Terminals 0-380V=340-520V
