Under the normal power supply of gpe4890asystem, various parameters of rectifier module and powerdistribution unit are controlled by monitoring module, and workaccording to their predetermined parameters or user commands. Incase of mains failure, the system will be powered by the battery atthis time. As the battery discharges, the battery terminal voltagebegins to drop. When the battery voltage is lower than 46v, themonitoring module reports the battery undervoltage signal. When thebattery voltage is lower than 44V, the battery will be powered off.When the external power supply is on, the system is workingnormally (the above monitoring data is the default value of thesystem, which can be reset by the user).
In addition to the battery dischargeprotection, the battery and load over temperature protectionfunctions are prohibited by default, and users can issue a command* * * or prohibit as needed. The working environment temperature ofthe power supply system shall be ≥ 55 ℃, and the power output ofthe power supply system shall be reduced.
