COSOUL was established in 2010, and has been focusing on the R & D, production and sales of high-frequency DC power supplies, synchronous rectifier power supplies, and single- and multi-output high-frequency pulse power supplies, providing stable, advanced, Efficient power supply solution. At the same time, the pulse power supply independently developed by our company has obtained 17 national technology patent certificates and a number of software copyrights.

The main products are:

◆ CSDC series: high-frequency DC power supply;

◆ CSDR series: high-frequency DC commutation power supply;

◆ CSPP series: high frequency positive pulse power supply;

◆ CSPR series: high frequency positive and negative pulse power supply;

◆ CSHP series: UHF pulse power supply;

CSDC series and CSDR series power supplies, designed output voltage range is 5-500VDC, the maximum output current manual mode can reach 64000A, the automatic mode can be expanded arbitrarily. The output ripple coefficient is controlled below 2% or 1%, the power conversion efficiency is over 87%, and the synchronous power efficiency is up to 95%. This series of products are widely used in electroplating (bathroom, auto parts, metal plating, etc.), electrochemistry, electrolysis , Oxidation, electrophoresis and other processes.

CSPP (positive pulse power) series has a design voltage range of 5-250V and a maximum output current of 64000A. It is mainly used in high-quality non-crack chromium and rare metal plating processes. CSHP (Ultra High Frequency Pulsed Power Supply) series products have played a very good role in the production of nano-materials, sewage treatment, and special surface treatment of military products. CSPR double-pulse (single, dual, multi-output) series products combine all the functions and features of DC power supply and pulse power supply. The technology is in the leading position in the industry. It is widely used in the PCB board industry through-holes and blind holes, especially In the high aspect ratio process, it has particularly outstanding performance. In the hard chromium industry, it has also achieved excellent results. In cooperation with customers, it successfully broke the 20um hard chromium neutral salt spray test and broke the 500-hour mark. The hardness reached above HV950.

After years of accumulation, the COSOUL brand is favorite by more and more users. The products are not only spread throughout the domestic market, but also exported to the United States, Britain, Germany, Poland, India, Indonesia, Malaysia, Vietnam, Taiwan and other countries and regions. It has been highly recognized and praised by users at home and abroad.
