The high-frequency power supply equipment (communication power supply) system can be combined according to the system capacity rectification module, the modules are automatically balanced, and the modules can be replaced online. The system high-frequency switching power supply (communication power supply) system can select multiple rectifier modules according to the system capacity. The module automatically divides the current, and the module can be replaced online, and the system capacity is convenient to expand. The monitoring module can reliably realize the intelligent management of the power system and the battery, and is equipped with a modem, and can also perform centralized remote monitoring through a public or private telephone network. Capacity expansion is convenient. The monitoring module can reliably realize the intelligent management of the power system and the battery, and is equipped with a modem, and can also perform centralized remote monitoring through a public or private telephone network. 1 Designed for the communication industry 2 Adopt international advanced high-frequency phase-shifting edge resonance technology, ultra-wide range power input, module adopts power factor correction technology, efficient and reliable 3 Automatic current sharing N+1 redundant modular design 4 The monitoring system realizes the rectifier module, the feeder input, the battery intelligent real-time tube monitoring system to realize the rectifier module, the feeder input, the battery intelligent real-time tube 5 with multi-level lightning protection measures, the system has strong impact resistance and fast dynamic response. Can be widely used in various communication equipment packages.
