Product Description

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
