Product Description
R449 generator avr 3 phase automatic voltage regulator
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
*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

 Steady state voltage regulation
 Remote voltage adjustment range ±5%
 Short circuit capability 3 x Irated for 10 seconds
 Voltage sensing 0-110v Terminals = 95 to 140 volts (50/60 Hz)
 0-220v Terminals = 170 to 260 volts (50/60 Hz)
 0-380v Terminals = 340 to 520 volts (50/60 Hz)
 Response time Normal (1 sec) for ± 20% voltage variation
 Rapid (0.3 sec) for ± 20% voltage variation
