48V DC rectifier 1U power supply system

48V DC rectifier 1U power supply system converter 220Vac to 48Vdc rectifier, to charge various batteries. 

The 48V DC embedded communication power supply system (Rectifier System) is suitable for small program-controlled switches, access networks, transmission equipment, mobile communications, satellite communications ground stations, microwave communications power supply, and can also be used for power supply for other communications equipment.

Under normal operation, various parameters of the rectifier module and power distribution unit are controlled by the monitoring module, and work according to their predetermined parameters or user commands. If the mains fails, the system will be powered by the battery at same time. As the battery discharges, the battery terminal voltage begins to drop. When the battery voltage is lower than the 46V dc (Alarm Value can be settable) battery low-voltage alarm point from monitor, the monitoring module reports an alarm. The recitifer will stop work. When the external mains power is restored, the system resumes working again.
