DIN rail power supply unit 48 V DC/5 A, primary switched-mode, 1-phase. The SFB technology (Selective Fuse Breaking Technology) can now also be used to trigger standard power circuit breakers reliably and quickly.
The Phoenix Contact QUINT-PS/1AC/48DC/5 is a primary-switched single-phase power supply unit designed for industrial automation applications requiring reliable 48 VDC power delivery. This third-generation QUINT POWER series device features SFB (Selective Fuse Breaking) Technology, enabling circuit breakers to trip magnetically at six times the nominal current for 12 ms to provide selective system protection and prevent DC bus collapse. The unit incorporates POWER BOOST technology for reliable starting of loads with high inrush currents, preventive function monitoring to diagnose impermissible operating states, and adjustable output voltage capability ranging from 5 VDC to 56 VDC. Designed for DIN rail mounting with pluggable screw connections, it offers wide-range input acceptance and is suitable for use in harsh industrial environments including compliance with ISA G3 Harsh Group A standards.
