Dazhong Electronics Co., Ltd., Dongguan, was established in 1992, with its headquarters located in the beautiful Dongcheng District of Dongguan City. The company specializes in the research, development, production, and sales of various high/low-frequency transformers, inductors, high-voltage transformers, toroidal transformers, potted transformers, three-phase power transformers, reactors, amorphous devices, chargers, power adapters, low-power switching power supplies, and other electronic components. These are widely used in photovoltaic systems, energy storage, wind power, new energy vehicles, network communications, UPS, rail transportation, data centers, industrial power supplies, robotics, server power supplies, home appliances, and other fields.

The company has obtained ISO9001:2015 International Quality Management System, ISO14001:2015 International Environmental Management System, and IECQ QC080000:2017 Hazardous Substance Process Management System certifications; as well as IATF16949:2016 Automotive Industry Quality Management System certification.

It operates five production bases in Dongguan, Heyuan, Luoshan (Henan), Longyan (Fujian), and Chongqing, with over 100 R&D engineers, 115 patents, an annual production capacity of 120 million components, and total sales of 1.2 billion yuan.

In 2016, the company drafted the national standard for small transformer and inductor design GB 19212.15-2016.

In 2017, the company won the Gold Award for charging piles.

In 2020, it was awarded the title of Provincial R&D Center.

In 2021, it received the title of Engineering Technology R&D Center for Power Transmission and Distribution Devices.

In 2022, it was recognized as a Municipal-Level Technician Workstation.

In recent years, the company has collaborated with several domestic universities, including South China University of Technology, Lanzhou University, Fuzhou University, Liaoning Technical University, Taiyuan University of Technology, Guangdong University of Technology, and Shanghai Jiao Tong University. Breakthroughs have been made in areas such as the development and industrialization of high-efficiency magnetic-electronic components for new energy vehicle charging piles, research and development of rare-earth easy-plane soft magnetic materials, development of megahertz high-frequency metal soft magnetic materials, optimized design of PFC inductors for variable-frequency air conditioners, optimized winding design for rotary loosely coupled transformers, R&D of 5G integrated miniaturized high-withstand-voltage three-phase transformers, and the development and industrialization of high-performance amorphous nanocrystalline soft magnetic alloy strips and magnetic devices for high-end electronic equipment in electric vehicles, as well as the development of 5kW and 10kW phase-shift ACDC power supplies. The company also actively cooperates with the magnetic materials, insulating materials, power supply chips, and semiconductor power device industries to promote the high-frequency, miniaturization, integration, and high-efficiency development of magnetic components, providing customers with more and more efficient services.
