Description:
Leroy somer R450 AVR is powered by two auxiliary windings which are independent of the voltage equal circuit. The power supply voltage is rectified and filtered before being used by the AVR monitoring transistor. With PMG excitation, a permanent magnet generator (PMG) added to the alternator supplies the AVR with voltage.
On Application of load, the rotation speed of the generator set deceases, when it passes below the preset frequency threshold the LAM causes the voltage to drop by approximately13% or 25% and consequently the quantity of active load applied is reduced by approximately 25% to 45%, until the speed reaches its rated value again. Hence the LAM can be used either to reduce the speed variation (frequency) and its duration for a given applied load, or to increase the applied load probable for one speed variation (turbo-charged engine).

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.
