EPS emergency power supply and DC screen is one thing, what is the difference between the two?
Mainly used in road traffic lighting, venue lighting, building fire escape lighting, fire pumps, spray pumps and other fire equipment to provide emergency power supply, EPS fire emergency power supply through the CCC China national compulsory product certification, the current state through the 3C certified EPS Fire emergency power supply size is 0.5KVA to 110KVA. EPS fire emergency power supply can be divided into emergency lighting, hybrid and power inverter EPS emergency power supply three categories.
EPS fire emergency power supply is a centralized fire emergency power supply, in the city power failure and abnormalities, to continue to supply power to the load to ensure that no power to protect people's lives and property security.
DC screen [1] is a short description of the DC power supply operating system. Universal name for the intelligent maintenance-free DC power supply screen, referred to as DC screen, universal model for the GZDW. Simply put, the DC screen is to provide a stable DC power supply equipment. (Directly converted to DC220V or DC110V when inputting 380V power supply, and input directly to battery power when input (mains and standby) are input - DC 220V or DC110V: it can be said to be an industry Dedicated emergency power supply). Power plants and substations in the power of power supply are now used in DC power supply, which for the control load and power load and DC accident lighting load to provide power, is the basis of contemporary power system control and protection. The DC screen is composed of crossover power unit, charging module unit, step-down silicon chain unit, DC feed unit, power distribution monitoring unit, monitoring module unit and insulation monitoring unit. It is mainly used in small power plants, hydropower stations, substations, and other users of DC equipment (such as petrochemical, mining, railway, etc.) for power substation and sub-circuit. Electrical protection and fault lighting and other occasions.
