Frequently Asked Questions (FAQs)
How can I buy static frequency converters wholesale from China?
If you are interested in purchasing static frequency converters in a large quantity from China, it is advisable to approach companies that are authorized representatives of such products or trading companies and ask them to give you quotations that would include the details of Minimum Order Quantity, the total waiting time for supplying the goods, and the shipping conditions and terms. Among the other steps that you will need to take are checking the certifications of the products like CE and RoHS, besides that, you will ask for some factory photos and test reports as well and authorize the inspection services before the products are shipped.
Can these converters be customized for specific voltage or frequency needs?
Yes, it is normal for a large number of Chinese manufacturers to offer custom services that include input/output voltage transformation as well as frequency converter setup modification, for example, if you need 50 Hz converted into 60Hz, and even control interfaces of your equipment. In the RFQ stage, it is a good idea to ask the following questions for the future of the product: remote monitoring, enclosure rating, cooling method, and compatibility with the UPSs or isolation transformers. Software and front panel language options are also on the list for the manufacturers that would feel good providing custom software or language options on the front panel where the product would be very much like their own-brand products relationships.
