Introduction

Leroy Somer AVR R449,AVRR449 for Leroy somer generator

The R 449 voltage regulator is of a shunt type. It is designed to fit as standard on A50 to A 54 alternators. It canbe supplied with power either by a power VT, or by the AREP field excitation system, or by a single-phase or 3-phase PMG. Using the R 726 external module, the regulator can control the power factor (2F) and can match the alternator voltage to the mains voltage (3F) prior to synchronisation.

The circuitry of the R449 Automatic Voltage Regulator (AVR) provides closed loop control of the alternator output voltage by regulating the exciter field current. The R449 can be powered by either AREP or the PMG field excitation systems and is fitted as standard on following alternators. The electronic components mounted in a plastic casing are sealed with opaque elastomer. Connection is via 2 connectors.

Characteristics

Voltage regulation +/- 0.5 % at steady state and constant speed.
Two phase voltage sensing.
Control 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 vibration and harsh environments.
The R 449 is compatible with other modules giving additional functions.(parallel operation, 3 phase sensing)
Alternators LSA 50.1, 51.2, 53, 54.
Compatible with the SHUNT, AREP+ PMI or PMG excitation system
