Specifications of Stamford MA330 AVR Automatic Voltage Regulator for Brushless
1. Directly Manufacturer
2. Over 15 years experience in generator field
3. OEM Service
Stamford MA330 AVR Automatic Voltage Regulator is a three phase
full wave, pulse width modulated type automatic voltage regulator
(AVR) and forms part of the excitation system of the brushless
generator. Excitation power is derived from a shaft mounted three
phase permanent magnet generator (PMG) which provides an isolated
delivers to the AVR direct circuits.
The independent PMG assures the performance of the AVR alongside
non linear loads and reduces the radio regularity interference on
the generator terminals.
The AVR senses the voltage on the key generator winding either
straight or via transformers. This signal is used to manage the
power fed to the exciter stator (and hence the main rotor) to
maintain the generator output voltage within the specified
restrictions, compensating for load, speed, temperature and power

Depending on various circumstances, three different delivery
methods have been taken: by sea, by air cargo and by express
*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
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.
