The 2866802 is a 1-output DIN rail mount primary-switched QUINT Power Supply with SFB (Selective Fuse Breaking) technology. The 2866802 is a compact power supply unit with maximum functionality and adjustable voltage. With the SFB technology, six times the nominal current for 12ms, even the standard power circuit-breakers can now also be triggered reliably and quickly. Faulty current paths are switched off selectively, the fault is located and important system parts continue to operate. Comprehensive diagnostics are provided through constant monitoring of output voltage and current. This preventive function monitoring visualizes critical operating modes and reports them to the control unit before an error can occur. Quick tripping of the standard power circuit-breakers using dynamic power reserve SFB technology.
