Quality type R449 Automatic Voltage Regulators
The circuitry of the R449 Automatic Voltage Regulator (AVR) provides closed loop control of the alternator output voltage by regulating the exciter field current. The R449 can be powered by either AREP or the PMG field excitation systems.
Voltage regulation = 0.5%
Short circuit capability = 3 x I rated for 10 seconds (AREP or PMG excitation)
Voltage sensing = 85 to 130 volts (50/60 Hz) or 170 to 260 volts (50/60 Hz) or 340 to 520 volts (50/60 Hz)
Response time = Normal (1 sec) for 20% voltage variation or Rapid (0.3 sec) for 20% voltage variation
Capable of remote voltage adjustment = 5%
