Leroy Somer R449 AVR Original Replacement for Brushless Generator
LEROY SOMER R449 AVR Original Replacement Automatic Voltage Regulator is built to fully replace the original version, same fit, form and function.
General Description / Specifications
The R 449 voltage regulator is of a shunt type. It is designed to fit as standard on A50 to A 54 alternators.
It can be 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 synchronization.
The circuitry of the R 449 Automatic Voltage Regulator (AVR) provides closed loop control of the alternator output voltage by regulating the exciter field current.
The R 449 can be powered by either AREP or the PMG field excitation systems and is fitted as standard on following alternators.
The electronic apparatus mounted in a plastic casing are sealed with opaque elastomericThe regulator includes:
> A main terminal strip (10 terminals) J1
> A secondary terminal block (5 terminals) J2
> A frequency selection terminal block (3 terminals) J3
> A quadrature droop potentiometer P1
> A voltage potentiometer P2
> A stability potentiometer P3
> An underspeed potentiometer P4
> A maximum excitation potentiometer P5
> A sensing selection jumper ST1
(single/3-phase with an external module)
> A response time jumper ST2
> A frequency selection jumper ST3
> An external voltage setting jumper ST4
> A LAM (load adjustment module) jumper ST5
General 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)
Applications
Alternators LSA 50.1, 51.2, 53, 54.
Compatible with the SHUNT, AREP+ PMI or PMG excitation system
The R449 is in Compliance with: IEC, VDE, NEMA, BS, CSA, UL508 CE low voltage

Depending on various circumstances, three different delivery methods have been taken: by sea, by air cargo and by express service.
*By sea. This is the most economical way of delivery. Suit for big quantity order, the delivery cost dramatically low and assist you in achieving maximum profit. It normally would take about one month for cargoes to reach their destination port.
*By air cargo. The advantage of air cargo is it costs much less time than delivery by sea. Generally it would take about one to two weeks for cargo reaching its destination.
*By express service. It is the most expensive way of delivery, but it is really quick and convenient. Normally this door to door service can deliver the goods to your company only in 3-5days. Fortunately, we have signed big discount contract with most express companies, such as TNT, DHL and UPS, to help our customers cut their delivery expenditure.
