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

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.
In most situations, we accept T/T (telegraphic transfer or wire
transfer) as the main payment method for normal orders. There are
other different payment methods which are listed below:
T/T(telegraphic transfer): For order value which is lower than 3000 USD, 100% payment need to
be made in advance. For order value which is higher than 3000 USD,
30% deposit need to be made in advance and the balance should be
transferred when cargo is ready for delivery.
Western union: western union could be accepted only when the cargo sent by
express service and do not need clear the custom in China.
PayPal: only be accepted for easy buy customers who delivery the goods by
express service and do not need clear the custom in China.
After you transferred the deposit or complete payment of an order,
please remember to send the copy of bank slip to our sales
personnel by either e-mail or fax as the evidence of payment.
1. Our warranty period is 12 months from the date when the goods have been notified as ready for despatch by us.
2. During the guarantee period, we will repair or replace any damage that under proper use appears in the goods, except for the incorrect operation.
