On June 16，2026, a director from a UPS (Uninterruptible Power Supply) manufacturer and distributor with significant market influence in South Korea visited our company. The client’s specific purpose for the visit was to select a qualified supplier of active power filter (APF) for their branch in Vietnam. We were honored to be the only APF manufacturer to be visited during the client’s trip to China.

To provide the client with a comprehensive understanding of our R&D and manufacturing capabilities, we warmly welcomed him to visit our factory in Zhongshan. During the visit, we show how we test active power filter by our independently developed load testing system and we presented the measurement data step-by-step, clearly illustrated the significant improvement of the current distortion rate THDi before and after connecting the active power filter. The client was impressed by the performance of our products and the reliability of our test results, recorded a video of the testing process, and promised to report to our headquarters in South Korea.

Then, we took our clients to our four production workshops for different products, demonstrating our production processes and showcasing our excellent production capabilities. Later, we led the client on a tour of our nearly 12,500 square meter warehouse and systematically introduced our other best-selling harmonic suppression products, including passive harmonic filters and EMC filters etc. Our technical team provided another customized solutions based on the client’s project needs of Vietnam factory, focusing on the differences between passive and active harmonic filters in terms of lifespan, cost, operation and applicable operating environments. The client highly appreciated our professional and systematic technical insights and expressed being deeply impressed by our knowledge and experience in harmonic suppression and power quality management.

The visit concluded successfully in a friendly and productive atmosphere. The client highly praised our warm hospitality, professional explanations, and strong production and testing capabilities, fully recognizing our product quality and overall corporate strength. He expressed his gratitude repeatedly and clearly indicated their intention to cooperate in the future. Both parties look forward to building upon this visit to deepen cooperation in power quality optimization and inverter peripheral applications.
