Description
The Phoenix Contact QUINT-PS/1AC/24DC/20 (Order No. 2866777) is a high-performance DIN-rail switch-mode power supply that converts a wide-range single-phase AC input (85–264 V AC) into a stable 24 V DC / 20 A (480 W) output. Part of the QUINT POWER family, it features NFC (Near Field Communication) configuration, integrated signal contact (DC OK / overload), and a robust metal housing for demanding industrial environments. It is ideal for powering PLCs, I/O modules, HMIs, sensors, and actuators in process automation, machine building, and infrastructure applications.
