The Phoenix Contact QUINT-PS-3X400-500AC/24DC/20 is a three-phase, primary-switched DIN rail power supply unit designed for industrial automation and plant engineering applications. It converts three-phase AC input voltage into regulated 24 V DC output with 20 A continuous current capacity. The unit features POWER BOOST technology that delivers up to 27 A for starting heavy loads with high inrush currents, ensuring reliable fuse tripping and system startup. The device incorporates preventive function monitoring with remote diagnostics via an active transistor switching output and floating relay contact. It offers wide-range input compatibility, accepting 320-575 V AC across all three phases, making it suitable for global deployment. The power supply is idling-proof and short-circuit-proof, with adjustable output voltage from 22.5 to 28.5 V DC. It can be connected in parallel for redundancy or increased capacity, and mounts horizontally on standard NS 35 DIN rail.
