Introduction

R449 automatic voltage regulator of generator avr 200kw

The circuitry of the R449 Automatic Voltage Regulator (AVR) provides closed loop control of the alternator output voltage by regulating the exciter field current. Which can be powered by either AREP or the PMG field excitation systems and is fitted as standard on

8100 Series Alternators & 9100 Series Alternators.

*Quad-rature droop adjustment

*Alternator output voltage adjustment

*Stability adjustment

*LAM Threshold (under speed) adjustment

*Excitation ceiling adjustment

*Selection of single phase or three phase* voltage sensing

*Selection of normal or rapid response time

*50 Hz or 60 Hz frequency option

*Remote voltage adjustment option

*LAM enable/disable option

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 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
