The QUINT-PS/3AC/24DC/20 is a DIN-rail mount primary-switched Power Supply with SFB technology. Compact power supply unit of the new QUINT POWER generation maximize the availability of your system. With the SFB technology (selective fuse breaking technology), six times the nominal current for 12ms, even the standard power circuit-breaker 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-breaker using dynamic power reserve SFB technology
• Reliable starting of difficult loads with static power boost power reserve
• Preventive function monitoring
• High operating safety due to long mains buffering under full load and high MTBF (>500000 hours)
• Perfect functioning even in the event of a permanent phase failure
• High surge voltage strength up to 6kV (surge, asymmetric) using an integrated gas arrester
• <0.5s Typical response time
• 40W Maximum power loss nominal load
• 11W Maximum power dissipation idling
• >93% Efficiency (at 400VAC and nominal values)
• IP20 Protection rating
