5. User guide

5.1 TB48XXF-T110X Operation principle and Wiring hint

Input AC 220V, after rectification power module, output DC 48V. When the power grid normal, the battery will supply power according to system requirement, and to be charged at same time; when power off, the battery will supply energy, to make sure the DC power system working normally, to realize uninterruptible power supply. The power supply has second disconnection function, when the battery voltage is low, the battery output would be cut off to protect battery.
