Descriptions:
The R438 voltage regulator module can be powered by AREP or PMG field excitation system.
95-480V automatic voltage regulator is must-have item for your brushless generator, suitable for for Leroy Somer.
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. Compatible with the AREP or PMG exitation system.
Electronic protection(overload,shortcircuit on opening of voltage sensing circuitexcitation overload current for 10 seconds
then return to approximately 1A).
Normal or rapid response time via ST2 jumper, voltage adjustment via potertiometer P2, quadrature drop adjustment via potertiometer P1,
max, excitation current adjustment via P5
