      1. GZD(W)

        Numerical control DC screen

        GZW series numerical control dc screen is suitable for the substation, power plants, communications, power systems and industrial and mining enterprises, as control, protection, signal, emergency lighting and other dc power supply load of normal and accident conditions. Especially suitable for unattended substation, it is below 500000 v ideal transformer substation dc power supply system.
        PLC+touch screen monitor and intelligent high frequency module,a new element such as lead-acid maintenance-free battery technology combination, and the power system of open configuration software and communication function continuously put forward higher request, in the field of the dc power supply, finally introduced a higher degree of automation, protection configuration is more reasonable, all-digital testing regulation and control of intelligent numerical control dc power supply Screen.
