3. Model CS1U-4820 Operating Principle
Under normal conditions, every parameter of rectifier modules and distribution unit are all under control of the monitoring module, operating according to the pre-set parameter or user’s commands. If AC mains fault, the system will be powered by the battery. With the battery discharge, the terminal voltage of the battery starts to descend. When the battery voltage is under 42V±0.5V, the monitoring module reports battery under voltage alarm signal and cuts off the load output, then the power system stops working. When the external AC mains recovers, the system will resume to the normal work state. (All above monitoring data are system default values that users can reset).
4. Rectifier Application
(1) Integration access
(2) Indoor distribution and extension system
(3) Mobile station and extension coverage system
(4) WLAN
(5) Satellite communication ground station and microwave communication station
(6) Weak current distribution room
(7) Other AC/DC uninterruptible power system
