R438 Leroy Somer Voltage Regulator
The R438 Automatic Voltage Regulator (AVR) is a high-precision and robust voltage regulation unit developed for LSA series industrial alternators. Compatible with SHUNT and auxiliary winding excitation systems (AREP / PMG), the R438 AVR ensures stable and reliable control of the alternator output voltage across a wide range of operating conditions. Thanks to its advanced electronic design, it provides fast dynamic response and minimizes voltage fluctuations during load variations. Equipped with overvoltage and low-frequency protection functions, the R438 AVR contributes to the safe and long-lasting operation of generator and alternator systems. With its compact design, easy installation, and proven performance in industrial applications, the R438 AVR is an ideal choice for generator sets, commercial power systems, and standby power solutions.
