Phoenix Contact 2904597 QUINT4-PS/1AC/24DC/1.3/SC – 24 V DC, 1.3 A Power Supply
The Phoenix Contact 2904597 (QUINT4-PS/1AC/24DC/1.3/SC) is the smallest single-phase, primary-switched DIN rail power supply in the fourth-generation QUINT POWER range. It delivers 24 V DC at 1.3 A (30 W) in a housing only 22.5 mm wide. A static boost to 1.625 A and a dynamic boost to 2.6 A for 5 s let it start heavy loads reliably. It also offers preventive function monitoring, a configurable signal output and an output adjustable from 24 to 28 V DC, bringing QUINT-level system availability to very compact control boxes.
