Product Description

Generator Automatic Voltage Regulator AVR Replacement Brushless Alternator R448 for Leroy Somer

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.
 
Steady state voltage regulation  ±0.5%
 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
