DC-DC Converters - Phoenix Contact


Phoenix Contact’s Quint SFB power supply line now includes DC-DC converters.  The new DC-DC converters can boost voltage over long wire runs, regulate battery voltage output and isolate ground loops. Thanks to Phoenix Contact’s Selective Fuse Breaking (SFB) technology, the converters provide up to six times nominal current for 12 milliseconds. 

The units also feature Power Boost technology, providing up to 125 percent of the rated output for demanding loads. The power supplies’ advanced diagnostics, including DC OK and Power Boost, make it easy to check status. The housings are made of extruded aluminum for improved cooling and longer service life.  This also decreases the heat load in cabinets. The converters carry UL 508 Listing and Class I, Div. 2 approval.
