Product Description
Brand New OEM Replacement, High Quality After Market Part Notice: 1PC
Notice: 1PC
Perfect fit, direct replacement. 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). 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 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).
