954-233 Automatic Voltage Regulator AVR R449 Compatible With FG Wilson Generator Alternator GensetPart Number: 954-233Compatible With: FG Wilson 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: 8100 Series Alternators 9100 Series AlternatorsCompatible Alternators : LSA51.2, LSA53.1 , LSA54Specification of R449 AVR: Steady state voltage regulation 0.5% Short circuit capability: 3 x Irated for 10 seconds (AREP or PMG excitation) 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) Response time:Normal (1 sec) for 20% voltage variation or Rapid (0.3 sec) for 20% voltage variation Remote voltage adjustment range: 5%Load Adjustment Module (LAM):On load impact, the rotation speed of the generator set decreases. When it paes 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 againShipment Time:1-2 Days After
