1、 Application Fields

BK48300AIt is a multifunctional, high-performance, intelligent integrated rectifier power supply designed and manufactured by our company for communication equipment. It consists of four parts: AC distribution unit, DC distribution unit, rectifier module, and control unit. The rectifier module model isBK4830A(48V/30A)orBK4820A(48V/20A). Can be placed at most12A module with a maximum capacity of180Aor300A，BK48300AMainly suitable for small and medium-sized exchange offices, mobile base stations, and various dedicated communication networks.

2、 Principle Introduction

Connect three-phase five wire AC power, and through the master-slave power switching unit, the AC distribution panel distributes the AC power to external electrical appliances and rectifier modules. The rectifier module uses high-frequencyPWMTechnology converts single-phase AC power into isolated DC power. The DC power is distributed to two sets of battery packs for charging and for supplying loads through the DC distribution unit. The control unit controls the entire system, achieving functions such as fault alarm, display, keyboard operation, battery management, remote communication, etc.
