Feature

●Normal AVR supply power:2 auxiliary windings (X1, X2, ans Z, Z2)
●Shunt supply: 150V - 5060Hz Rated overload current:10A, 10s.
●Electronic built- in )overload, short circuit, and loss of sensing) protecting: If excitation current raises over 10 amps for more then 10 seconds, excitation current will drop automatically to about 1A.
●To reset AVR protection, the 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 voltage taps at: Terminals 0 - 110V = 95 to 140V. Terminals 0 - 220V = 170 to 260V. Terminals 0 - 380V = 340 to 520V


Description

The R448 Automatic Voltage Regulator (AVR) is an advanced electronic component that provides closed loop control of the generator output voltage.

• The Automatic Voltage Regulator (AVR) is an advanced electronic component that provides closedloop control of the generator’s output voltage.
• Normal AVR supply power:2 auxiliary windings (X1, X2, ans Z, Z2). Shunt supply: 150V - 5060Hz. Rated overload current:10A, 10s.
• Electronic built- in )overload, short circuit, and loss of sensing) protecting: If excitation current raises over 10 amps for more then 10 seconds, excitation current will drop automatically to about 1A.
• To reset AVR protection, the 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 voltage taps at:

• Terminals 0 - 110V = 95 to 140V
• Terminals 0 - 220V = 170 to 260V
• Terminals 0 - 380V = 340 to 520V
