Dongguan Feirui Electronics Co., Ltd. is located in Donguan City, which is known as "the World's Factory" in China. We are engaged in developing and producing engine parts including starting controllers, speed control units, automatic voltage regulators (AVR), synchronizers, load share modules, and other correlative generator accessories, such as chargers, sensors, actuators and other related products.
We have emulational system which is the most advanced in the same industry. The system can imitate the whole process of real generator. Therefore, we can control our quality with the precise testing equipment. On the other hand, we own some generator experts with rich experience in electromechanical automatic control system. Being good at soft ware & hard ware, these experts are trained by some well-known diesel engine factories. With about 10 years' experience and skill, we can supply the best technology support service. According to customers' requirements, we can develop some special products and supply OEM service.
Due to our unremitting efforts for many years, we have set up wholesalers in Nigeria, Egypt, Thailand and Philippines. Following the ideal of "Quality First, Credit and Service is Our Belief ", we strive for innovation to make satisfied generator parts. We expect to create more achievement tomorrow and welcome you to contact us for cooperation.
