AVR R438 Automatic Voltage Regulator Fit For Leroy Somer Generator

Key Features:

• 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
• 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
• Applications to Alternators: LSA 42.2,43.2,44.2
• Compatible with the AREP or PMG exitation system
