Phoenix Contact 1110466 UNO2-PS/1AC/24DC/120W – 24 V DC, 5 A Power Supply
The Phoenix Contact 1110466 (UNO2-PS/1AC/24DC/120W) is a single-phase, primary-switched DIN rail power supply. It belongs to the new UNO2 generation of the Phoenix Contact UNO POWER range. It delivers 24 V DC at 5 A (120 W) in a housing only 35 mm wide, with typical efficiency of up to 94%. The output voltage can be adjusted from 24 to 28 V DC. The first-generation UNO units only have a status LED, but the UNO2 adds a DC OK LED and a floating DC OK switching contact for remote monitoring.
