5.Operating Principle


After AC power is controlled by the AC hydraulic switch and then through the EMI board lightning protection and filtering processing, into the rectifier module, AC hydraulic switch has the function of overload and short circuit protection to AC power.


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 -46.2V±0.5V, the monitoring module reports battery under voltage alarm signal; When the battery voltage is under -45.6V±0.5V, close LVLD load output; When the battery voltage is under -43.2V±0.5V, close LVBD 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).


6. Installation


GPE4890J is embedded power system. First insert GPE4890J to the specified location till the system is well fixed. Keep the 4 fixing holes on the bracket in line with those on the cabinet and then screw up 4 M6 cross rounded head screws, with the spring washer and flat washer. At last finish the installation after tightening the screw.
