Zhongshan Huaxing Power Supply Technology Co., Ltd is one of famous high-frequency switch power supply R&D and manufacturing enterprises all over China, and also one of new-/hi-tech enterprises affiliated by Zhongshan Torch Industry Alliance Co., Ltd (in national-class new-/hi-tech development zone). This company locates at Zhongshan, regarded as hometown of great master and famous as beautiful scenery here, where this features convenient traffic facilities, developed, integral and all-ready information communication facilities. This Company holds all-ready production facility and stronger technical power. 45% staff has academic background for junior college/technical student, with about 2000 sets of high-frequency switch power supply per year.

Over past ten years, this Company teamwork is always dedicated to develop and produce big-power switch power supply and rich experience in research and development for switch power supply. Key technology has been awarded as several national patents. In addition, we jointly met China Academy of Science, Xi’an Jiaotong University and international switch power supply institute and set up better cooperation relationship and R&D platform.

Over past many years, this Company set up perfect production management system, quality control system and sales-before/after management system, and certified with ISO9001：2000 international quality system certificate. Huaxing Power Supply product has been hotly sold all over China and even South Korea, South Africa and Taiwan and other countries and regions. Currently it has set up sales office in Zhengzhou, Shenyang, Chengdu and Shenzhen, and promptly provides with hospitable service for customer. This Company also regards customer satisfaction as strictest standard for work evaluation and focuses on product quality and after-sales service.

Regarding self-responsibility for providing user with high-property, high-efficient and high-reliable product, we succeed to practice standard named as being responsible enterprise and being a responsible person. We would like to hand by hand march on and mutually develop.

1.Leading international high-frequency transformer technology

This transformer is optimal selection for big-current output switch power supply, it is socket-mode structure, it features large conductive area, integration in air-cooling and water-cooling application, simple structure and good-looking appearance, and easier to quantitative production. Currently it has obtained four new-designed patents and has declared national inventive patent.

2.Optimal water-cooling structure

Water-cooling switch power supply is optimal for massive customers; it features better cooling, lower noise and less compactness. Over past many years of practices, Huaxing Company has compact water-cooling power supply key power loop, reasonable watercourse, all these have been consistently approved among national and international customers.

3.Available computer control system

Under demand for user, this provides PLC-based power supply control system and SCM telecommunication system, easier implementation for automatic control and integral management.

4. Available super-power switch power supply

Currently, this Company has pushing forward 20000A24V super-power switch power supply. This power supply is applicable for galvanization site for galvanized plate and relevant sites. This applies for N+1 parallel connection, effectively assures even distribution for module-between current stress and thermal stress and prevents one set or several sets of module operating under current limit. Since parallel connection-operated module is not inconsistent, better-feature (less voltage adjustment) module may undertake more current, even overload, so this makes worse-feature module may run under light load, even basically for no-load. Its result consequentially is module sharing in more current and big thermal stress, so this shall greatly reduce reliability.
