• Description:
  • Voltage regulation +/-0.5% at steady state and constant speed
  • Phase to phase voltage sensing
  • Controls by transistor means the regulation quality is independant of load applied
  • Integrated "LAM" system to cope with increased loads applied to the engine
  • Suitable for high levels of viration and harsh environments
  • The R438 is compatible with other modules giving additional functions
  • Standard power supply: AREP or PMG
  • Rated overload current: 8A-10s
  • Electronic protection(overload,shortcircuit on opening of voltage sensing circuitexcitation overload current for 10 seconds then return to approximately 1A).
  • Fuse: F1 on X1,X2.8A;slow-250V

    • Automatic Voltage Regulator AVR R438 For Leroy Somer Generator US
