Phoenix Contact 2904598 QUINT4-PS/1AC/24DC/2.5/SC – 24 V DC, 2.5 A Power Supply
The Phoenix Contact 2904598 (QUINT4-PS/1AC/24DC/2.5/SC) is a compact, single-phase, primary-switched DIN rail power supply from the fourth-generation QUINT POWER range. It delivers 24 V DC at 2.5 A (60 W) in a housing only 32 mm wide.
It handles heavy loads in two ways:
- Static boost: 3.125 A continuous.
- Dynamic boost: 5 A for 5 s, for starting heavy loads.
It also offers preventive function monitoring, a configurable signal output and an adjustable output from 24 to 28 V DC. It suits small control cabinets where high system availability matters.
