The DC power supplies of the GENESYS + series are optionally available without a control element. The blank front panel GB30-112-IEEE-1P is used as a power supply if no own device control via a display is required. With the exception of the display functionality, it offers all the powerful standard functions of a GENESYS + power source and is used as a slave module in parallel or series connection with a master power supply unit (with control unit). The blank front panel is controlled via the digital interfaces (LAN, USB, RS-232/485) or via the isolated analog interface.
