Product Description
Overview
With the wide application and development of power electric technologies, there are more and more nonlinear loads in the power system, such as rectifiers, frequency converter, UPS, household applications, LED lights, computers and other equipment, and harmonic pollution in the grid is becoming more and more serious. At the same time, the power factor of most power electric devices is very low, which brings extra burden to the grid. In addition, the negative sequence current generated by three-phase asymmetric load also poses a series hazards to the power system and users, and has a significant impact on power supply quality. The automation and intelligence of the product process, as well as varies complex precision equipment, have put forward higher requirements for power quality. The harmonics have seriously affected the system safety and power supply quality, so its control has become an urgent problem to be solved in the power system.Features:
Relying on the advanced intelligent monitoring technology, it has the features of faster, smaller, higher performance, simper and faster improvement of power quality. Quick response: the response time of APF is less than 300us, making the harmonic eliminated before causing harm.Highly integrated: the 25A filter has a compact design and is easy to install, and the 500A filter also minimizes the size while ensuring excellent performance.Easy to maintenance: the APF benefits from its excellent design, the control unit modularization greatly shortens the repair and maintenance time.Multiple choices: have products with various specifications and capacities ranging from 50A-900A.Adaptability: can compensate for self-interference and automatically change network topology.
