ESP30-4815A GPON OLT Description:
ESP30-4815A GPON OLT power supply system is powered by a mains power supply. The AC power supply passes through the AC socket and then undergoes EMI filtering processing, and then enters the rectifier module. The DC output of the rectifier module is summarized by the power distribution unit and divided into two branches to supply power to the load.
The two branches are respectively FU-1 (10A), FU-2 (20A) fuse is controlled to provide users with overload and short circuit protection for each load. The user’s battery is connected to the DC output side of the power system through the battery fuse FU-BT (20A) and the electrical contactor KM1. The battery fuse provides overload and short circuit protection to the battery.
