1, Haiyun
The brand of PC power supply in Taiwan Province, China was founded in 1975. Since its establishment, Haisheng has been focusing on the research, development and production of high-quality power conversion products. 198 1 year, haisheng expanded its production to the field of PC power supply and became the leading brand of power supply manufacturing.
2. Zhenhua
The digital brand of Zhenhua Computer Co., Ltd. was established in 199 1. Super Flower is a brand specializing in the production of customized power supplies such as switching power supplies, computer cases and IPC industrial servers. Super Flower has actively invested in the research and development of high-end power supply market, and has passed a number of patent applications to provide power suppliers with products with stable quality, long service life and higher conversion efficiency.
3. Quanhan
1993 launched the power supply manufacturing brand belonging to Quanhan Group. Quanhan is a modern niche brand specializing in R&D and power supply manufacturing in the world. Adhering to the management concept of "service, specialty and innovation", the company has excellent management team, professional R&D engineering and technical team, huge production scale and complete product line, and its products cover green power supply in industrial computers, server systems, medical care, LCD digital TV, SSL and other fields.
Product classification of modular power supply:
1, green module power supply
The rapid development of computer technology leads mankind into the information society, and also promotes the rapid development of modular power supply technology. In the 1980s, computers adopted switching power supply in an all-round way, taking the lead in replacing computer power supply. So switching power supply technology has entered the field of electronic and electrical equipment. With the development of computer technology, green computer and green module power supply are put forward. Green computers generally refer to personal computers and related products that are harmless to the environment.
2, high frequency switch
The rapid development of communication industry has greatly promoted the development of communication power supply. High-frequency miniaturized switching power supply and its technology have become the mainstream of modern communication power supply system. In the field of communication, rectifier is usually called primary power supply, while DC-DC converter is called secondary power supply. The primary power supply is used to convert a single-phase or three-phase AC power grid into a DC power supply with a nominal value of 48V.
3. Converter
A DC/DC converter converts a fixed DC voltage into a variable DC voltage. This technology is widely used in stepless speed change and control of trolleybuses, subway trains and electric vehicles. At the same time, the above control can achieve the performance of acceleration, stability and rapid response, and at the same time, it can save electricity.
