FAQ

Q 1. what's the payment terms?

A. We accept LC, T/T, PayPal, Western Union, Small-amount payment, Money Gram

Q 2. how's the delivery time ?
A. usually it will take about two weeks for production

Q 3. tell me the standard of package?
A. For the small capacity, it use carton, but for big capacity, we should use strong wooden case for protection.

Q 4. what kind of material of transformer?
A. For servo type stabilizer,we have two types, one 100% copper and the other is copper with aluminum.It depends on your requirment. In fact,those two have no difference if normal work well. Only except the longlife. Copper is better and also higer price.For relay type stabilizer,we use toroid coils, the material is aluminum. comparing with square coils,toriod coils with high efficiency.

Q 5.Could you offer Form A or C/O ?
A. It totally not a problem. We can prepare relative documents to forgin affairs office or other office to apply for this certificate.

Q 6.Would you accept to use our logo ?
A.If you have good quantity,it absolute no problem to do OEM.

Q 7.We want to know month capacity.
A. It depends on which model.For example for relay type small capacity , month capacity can reach near 10000pcs and big capacity near 2000pcs.

Q 8.Where is your market?
A. Our products are popular inNorth America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, Mid East, Eastern Asia, Western Europeand so on.Some of them are our regular customers and some of them are developing. We hope you can join us and make mutural benifit from our cooperation.
