Description
The Phoenix Contact QUINT-PS/3AC/24DC/40 (Order No. 2866792) is a high-performance DIN-rail switch-mode power supply that converts a wide-range three-phase AC input (320–575 V AC) into a stable 24 V DC / 40 A (960 W) output. It is part of the QUINT POWER family, featuring NFC configuration (on NEO variants), integrated signal contact (DC OK / overload), and a robust metal housing for demanding industrial environments. Also listed are related QUINT models: QUINT-PS/1AC/24DC/20 (2866705), QUINT-PS/3AC/24DC/20 (2866734), and QUINT-PS/1AC/24DC/10 (2866802) — covering single-phase and lower-current options from the same family.
