With the development of communication network in the direction of wide coverage and deep extension, the power supply demand of various base stations, marginal computer rooms and transmission nodes continues to grow, and the problems of long deployment period, difficult operation and maintenance and insufficient system stability of traditional distributed power supply configuration are gradually highlighted. The integrated communication power supply cabinet highly integrates functional units such as rectification, power distribution, energy storage and monitoring, and becomes the core deployment scheme of 48V communication power supply system in a standardized and integrated form.
