[0002] DC panel is the abbreviation of DC operating power supply system. The general name is intelligent maintenance-free DC power panel, abbreviated as DC panel. DC panel is used to supply this DC power supply. DC panel is a device that provides stable DC power supply. When there is 380V input power, it is directly converted into 220V. When there is no input of AC power and backup power, it is directly converted into battery power supply - DC 220V: In fact, it can also be said to be an industrial-specific emergency power supply.

[0003] The lithium-ion DC screen in the prior art is generally dual-voltage, which means that it can be directly connected to the high voltage of the power grid to convert 220V for power transmission. At the same time, when the power is off, the lithium-ion battery in the cabinet can be used to power the equipment. However, when the DC screen in the prior art is powered by lithium-ion batteries, it is necessary to dissipate heat for the battery pack, and the filter in the cabinet inside it generally does not have a cleaning function. After long-term use, dust accumulates on the surface of the filter, which reduces the effect of heat discharge from the inside of the cabinet. Therefore, we need a lithium-ion DC screen with dual voltage output. Utility Model Content
