The Phoenix Contact QUINT-PS-100-240AC/24DC/2.5 is a primary-switched DIN rail power supply delivering 24 V DC at 2.5 A (60 W nominal output). It accepts wide-range AC input from 100–240 V AC (85–264 V AC operating range) or DC input from 90–350 V DC, making it suitable for varied industrial power environments. The unit incorporates transient surge protection via varistor and features a 5 A internal slow-blow fuse with permissible backup fuses B6, B10, or B16 for AC applications. Output voltage is adjustable from 22.5 V DC to 28.5 V DC via potentiometer, with exceptional line and load regulation of ±0.1% each. Efficiency exceeds 86% at nominal load. Mains buffering extends beyond 30 ms at 120 V AC and 130 ms at 230 V AC, protecting downstream circuits during supply interruptions. The POWER BOOST functionality enables reliable startup of loads with high inrush currents, typically under 20 A with an inrush current integral (I²t) below 2.2 A²s.
