SX460 automatic voltage regulator AVR for generator
SX460 is a half-wave phase- controlled thyristor type Automatic Voltage Regulator and forms part of the excitation system for a brushless generator.
In addition to regulating the generator voltage, the AVR circuitry includes under speed and sensing loss protection to ensure safe, reliable control of the generator.
Positive voltage build up from residual levels is ensured by the use of proficient semiconductors in the power circuitry of the AVR. Which is linked with the main stator windings and the exciter field windings to offer closed loop control of the output voltage with load regulations of +/- 1.5%

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.
