System Schematic:

Applications:


Widely used in communication and industrial fields. All of its communication power technology converts alternating current to direct current to supply power to the DC load, connects the battery pack in the power system to charge the battery pack, and detects the battery pack status. Three hot-swappable rectifier module ports can form an N+1 redundant system to provide fault tolerance for the load. In order to adapt to different external power supply systems, the monitoring system is equipped with 45 different alarm options. The monitoring screen can display current alarm information, query historical alarm information, and support RS485/SNMP remote operation.
