What should I look for when choosing a static frequency converter manufacturer?

To choose a Chinese static frequency converter producer wisely, take into consideration quality of the product, certificates like ISO and CE, and the record of application cases that deal with marine and industrial motors. Have a look at the service offer, availability of test reports, and options for harmonic filtration for it to be in line with the system requirements. Take into account the ability for export, lead time, and post-sales services covering spare parts and technical assistance.

How do China’s static frequency converters compare in price and performance to other suppliers?

Exclusive voltage converters in China are commonly competitively priced, thanks to the low costs of manufacturing and labor, but they still deliver high performance through the use of well-established SFC designs and sourcing of components. Performance-wise, it is possible to bring the Chinese converters to the same level as the international brands by using top-quality IGBTs and DSP control, as well as by providing for good cooling, such as water and air cooling. So be sure to check the performance test data, efficiency curves and other certificates provided to ensure the reliability and the quality of the machines.

Can a manufacturer provide customization for specific applications?

Yes, the Chinese market is characterized by a lot of manufacturers that can supply customized inverters for specific applications like air-conditioning, marine, oil and gas, and renewable energy systems. The kinds of customization that are usually offered in these cases are mostly new control logic, IP enclosure ratings, communication protocols like Modbus or Profibus, and the addition of certain specific harmonic filtering arrangements, if necessary. The key is to document the specifications—it can be a pain, but it is a necessary step as it will help you avoid many warranty-related issues in the future.

What certificates and examinations must one demand from a producer?

You must absolutely demand the following certificates: ISO 9001, CE, and, if relevant, and ABS or DNV in the case of marine use. Make the manufacturer perform a factory acceptance test (FAT) and provide a report. Clients should also require an EMC test and that the equipment comply with the safety standards. Besides, performance verification is very important because it lets you know the under THD, efficiency, and measurements. These are all aspects of the documentation that the manufacturer needs to have to make sure that the converter will be capable of meeting the grid integration requirements. It will definitely reduce the possible risks associated with getting approval from regulatory bodies on both imports and local installations, respectively.
