New Generator AVR R438 Automatic Voltage Regulator for Leroy Somer

Main characteristics:
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).

Voltage sensing: 5VA isolated via transformer
0-110V terminals=90-140V
0-220V terminals=170-260V
0-380V terminals=340-520V
Voltage regulation +/-1%
Normal or rapid response time via ST2 jumper
Voltage adjustment via potertiometer P2
Current sensing(parallel operation): C.T. 2.5VA cl1,sencondary 1A(optional)
Quadrature drop adjustment via potertiometer P1
Max,excitation current adjustment via P5
