Standard Embedded Communication Power Supply

Introduction

AF4800 Series Standard Embedded Communication Power Supply System is a DC uninterruptible power supply product tailored and independently developed by Afores mainly for my country's communication fields such as mobile communications, satellite communication ground stations, microwave communication power supply, small programmable switches, telecommunications equipment, local area networks, communication room base stations, etc. This series of communication power supply systems adopts full-bridge soft switching technology with high efficiency, up to 92% or more. The rectifier module adopts non-destructive hot-swap technology, plug and play, and the replacement time is less than 1min. Perfect battery management, with load power-off and battery low voltage protection (LVLD + LVBD) and secondary power-off functions, can realize temperature compensation, automatic floating charge control, automatic voltage regulation, battery capacity calculation, online battery detection and other functions. The system adopts a networked design, provides a variety of communication interfaces (such as RS485, dry contacts), flexible networking, and can realize local and remote monitoring without human intervention. The system also has complete fault protection and fault alarm functions, complete AC and DC lightning protection design, suitable for areas with frequent thunderstorms. Full front operation and maintenance, can be installed against the wall, effectively saving space. Ultra-low radiation, using advanced electromagnetic compatibility design, the rectifier module can meet the "Electromagnetic Compatibility Limits and Measurement Methods of Communication Power Supply Equipment" (Communication Industry Standard YD/T983 of the People's Republic of China).
