Integrated high voltage rectifier is the newest kind of products of our company, which integrates total circuits into a part. Because of the integrated structure, this kind of products takes little influence of shocking, temperature, air, dust and oil, even can work well in the tough temperature. This kind of products can be used as the ideal and stable DC high voltage rectifier for photomultiplier, ionization chamber as well as similar testing equipment with the need of high voltage and low leakage current.
