Problems solved by technology

However, with the development of science and technology, the user's demand for isolated high-voltage module power supply is increasing. Due to the isolation of the input and output of the isolated high-voltage module power supply, and the requirement of insulation withstand voltage, the power supply products generally have large dimensions and heavy weight. Not easy to PCB mount

Description

technical field [0001] The invention relates to a fixed output isolated high-voltage module power supply used in mass spectroscopy and solid surface analysis, high-energy physical detection, semiconductor element detection system, environmental monitoring and dust particle counter, medical application and other instruments and equipment. Background technique [0002] Most of the existing low-power high-voltage modular power supply products on the market are designed for common ground, that is, the input and output share the same ground. They are relatively simple to manufacture and easy to make small. However, with the development of science and technology, the user's demand for isolated high-voltage module power supply is increasing. Due to the isolation of the input and output of the isolated high-voltage module power supply, and the requirement of insulation withstand voltage, the power supply products generally have large dimensions and heavy weight. Not easy to PCB moun...
