The Phoenix Contact QUINT-PS/3AC/24DC/5 is a primary-switched DIN rail power supply unit designed for industrial automation applications requiring reliable 24 V DC power. This unit features SFB (Selective Fuse Breaking) technology that magnetically trips circuit breakers at six times the nominal current for 12ms, enabling fast and selective protection. The power supply incorporates Power Boost technology, providing a static power reserve up to 1.5 times the nominal current to reliably start heavy loads with high inrush currents. It includes preventive function monitoring that diagnoses critical operating states before failures occur, enhancing system availability. The unit accepts 3-phase AC input and provides a regulated, adjustable DC output. Suitable for harsh industrial environments, it is tested to ISA G3 standards and is short-circuit-proof and idling-proof.
