Automatic Voltage Regulator

Brand: Leroy Somer

Model:R449 AVR

Part Number: RGT-HYG13

Description

The R449 automatic voltage regulator (AVR) for the LSA series of industrial alternators provides excitation current up to 7 A with excellent reliability for SHUNT, permanent magnet (PMG), or AREP excitation types. R449 is an analog AVR. It is designed for alternators with an AREP or PMG excitation. R449 controls the excitation current in order to maintain the output voltage of the alternator. R449 is performant in terms of voltage regulation, simple to set and use, and reliable.
