General Description / Specifications

For both AREP & PMG excitation systems, the alternator voltage regulator is the R129. With AREP excitation,

the R129 electronic AVR is powered by two auxiliary windings which are independent of the voltage match circuit.

For connections and adjustments are:

> main terminal strip J1 (10 marked terminal)
> 2 terminal strips J2 and J3 (2 marked terminals)
> potentiometer (screw) droop : P1
> potentiometer (screw) voltage : P2
> potentiometer (screw) frequency : P3
> potentiometer (screw) stability : P4
> potentiometer (screw) excitation ceiling: P5
> potentiometer (screw) internal voltage droop: P6
> ST1 50 Hz - 60 Hz
> ST2 with or without R 731

General Characteristics
> Negative action A.V.R. (diverting excitation current)
> Voltage accuracy ±1% between no-load and full rated load
> Voltage range adjustment with internal potentiometer (P2)
> Sensing input 220V: 170 to 250 V
> Sensing input 380V: 340 to 500 V
> Remote trimmer 470Ω-1W (Range ± 10%)
> Sensing input power 2VA, single phase, insulated by transformer.
> Rated controlled power (DC): 90V-7A -
> Peak power (10 seconds): 100V - 10A
> Rated diverted current 4 Amp, peak 10 A.
> Remote trimmer 470Ω -1W
> EMI Suppression
> U/F

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.
