AVR R449 Automatic Voltage Volt Regulator For Generator Alternator GensetThe circuitry of the R449 Voltage Regulator AVR provides closed loop control of the alternator output voltage by regulating the exciter field current.The R449 Leroy Somer AVR can be powered by either AREP or the PMG field excitation systems and is fitted as standard on following alternators: Ø 8100 Series AlternatorsØ 9100 Series AlternatorsCompatible Alternators : LSA51.2, LSA53.1 , LSA54 Specification of R449 AVR: Ø Steady state voltage regulation ± 0.5%Ø Short circuit capability: 3 x Irated for 10 seconds (AREP or PMG excitation)Ø Voltage sensing:0-110v Terminals = 95 to 140 volts (50/60 Hz) or0-220v Terminals = 170 to 260 volts (50/60 Hz) or0-380v Terminals = 340 to 520 volts (50/60 Hz)Ø Response time:Normal (1 sec) for ± 20% voltage variation or Rapid (0.3 sec) for ± 20% voltage variationØ Remote voltage adjustment range: ± 5%Load Adjustment Module (LAM):On load impact, the rotation speed of the generator set decreases. When it passes below the preset frequency threshold, the LAM causes the voltage to drop by approximately 15% and consequently the amount of active load applied is reduced by approximately 25% until the speed reaches it's rated value againAdjustment capability of R449 Alternator AVR:The R449 Voltage Regulator features the following adjustment capabilities (Please note that no adjustments should be made prior to careful consultation of the alternator installation and maintenance manual):Quadrature droop adjustment Alternator output voltage adjustment...
