The difference between a DC screen and a UPS is:
 
1, different applications; DC screens are mainly used to provide operation power or control power for switchgear, comprehensive protection devices, etc. UPS mainly provides backup power for computer rooms, computers and so on.
 
2, the principle is different. The DC screen is to convert AC into DC power and supply the external load. The principle of UPS is to rectify the alternating current into DC, and then through the inverter unit, DC will be converted into alternating current to supply the external load. In the case of electricity failure, the two are supplied by the battery group.
